Assessing the efficacy and safety of STOP (successful treatment for paranoia)—an app-based cognitive bias modification therapy for paranoia: a randomised clinical trial protocol

BackgroundParanoia, the belief that you are at risk of significant physical or emotional harm from others, is a common difficulty, which causes significant distress and impairment to daily functioning, including in psychosis-spectrum disorders. According to cognitive models of psychosis, paranoia may be partly maintained by cognitive processes, including interpretation biases. Cognitive bias modification for paranoia (CBM-pa) is an intervention targeting the bias towards interpreting ambiguous social scenarios in a way that is personally threatening. This study aims to test the efficacy and safety of a mobile app version of CBM-pa, called STOP (successful treatment of paranoia).MethodsThe STOP study is a double-blind, superiority, three-arm randomised controlled trial (RCT). People are eligible for the trial if they experience persistent, distressing paranoia, as assessed by the Positive and Negative Syndrome Scales, and show evidence of an interpretation bias towards threat on standardised assessments. Participants are randomised to either STOP (two groups: 6- or 12-session dose) or text-reading control (12 sessions). Treatment as usual will continue for all participants. Sessions are completed weekly and last around 40 min. STOP is completely self-administered with no therapist assistance. STOP involves reading ambiguous social scenarios, all of which could be interpreted in a paranoid way. In each scenario, participants are prompted to consider more helpful alternatives by completing a word and answering a question. Participants are assessed at baseline, after each session, and at 6, 12, 18 and 24 weeks post-randomisation. The primary outcome is the self-reported severity of paranoid symptoms at 24 weeks, measured using the Paranoia Scale. The target sample size is 273 which is powered to detect a 15% symptom reduction on the primary outcome. The secondary outcomes are standardized measures of depression, anxiety and recovery and measures of interpretation bias. Safety is a primary outcome and measured by the Negative Effects Questionnaire and a checklist of adverse events completed fortnightly with researchers. The trial is conducted with the help of a Lived Experience Advisory Panel.DiscussionThis study will assess STOP’s efficacy and safety. STOP has the potential to be an accessible intervention to complement other treatments for any conditions that involve significant paranoia.Trial registrationISRCTN registry, ISRCTN17754650.

Migrating Mobile Applications to the Web: Adult Crash Cart Training.

Nurses and clinicians require knowledge and training of their facilities' code blue response cart to manage emergency scenarios. However, the nurses who access the carts change frequently through turnover and role changes. An augmented reality training solution was built for mobile devices, but encountered distribution and access challenges. This study evaluated the conversion of the mobile application to a desktop-based version deployed via a learning management system. Eight hundred fifty clinicians were assigned the interactive learning product, which collected anonymous usage data and an optional feedback survey within the module. Of 850 assigned users, 468 completed the module, and 338 completed the feedback survey. Respondents indicated a positive difference of 25.3% in retrospective pre/post confidence and an appreciation for the features of the product. Performance measured by decreasing total item search time appeared to level off after three plays. The format transition was successful, allowing the same widespread distribution as the mobile versions of [X]. Feedback gathered will drive improvements in the module.

Academic journal website from the user’s perspective

Professional community recommendations on the content of academic journal websites mostly include criteria for indexing in databases, however these recommendations do not consider the authors’ and reviewers’ perspective on the website contents and design. To address this, we analyzed these recommendations through a survey of 198 Russian academic journal authors and reviewers, using a continuous sampling technique. The survey took place in April and May 2024. The questionnaire was based on the Principles of Transparency and Best Practice in Scholarly Publishing by COPE, DOAJ etc. The survey also focused on the journal website content, design, mobile version, and publication strategy of academic journal website users. We analyzed the survey results for two partially overlapping sets of authors who published in journals indexed in the Web of Science Core Collection, Scopus, and Russian Citation Science Index Core, or in journals listed by the Higher Attestation Commission of Russian Federation. The study revealed that both COPE’s recommendations and users of academic websites value information regarding aims and scope of the journal, copyright fees, review policies, timelines for the editorial and publication process, and licensing. However, Russian authors and reviewers put less emphasis on website sections that address ethical principles and authorship criteria. They prioritize having an online editorial office, security certification, scientific journal indexing and abstracting information, additional educational materials, and the ability to customize the website for devices with different screen sizes. We also discuss the importance of HTML meta tags for promoting the journal’s website. The findings of the research may contribute to promotion of Russian academic journals in international databases, improve the efficiency of communication between authors, reviewers and editors, and develop a set of recommendations that complement international publishing conventions.

Non-destructive detection of male and female information in ducklings based on near-infrared spectral wavelength selection and deep learning

The technology for sex identification in ducklings can contribute to increased revenue and cost savings in modern duck farming. However, traditional manual identification techniques require high skill levels and involve significant labor intensity. In this study, a non-destructive, user-friendly, and efficient duckling sex identification technique was proposed using near-infrared spectroscopy and deep learning algorithms. Spectral data from 600 groups of newly hatched ducklings were collected. These data were divided into training, testing, and validation sets in a ratio of 7:2:1. The raw spectral data was preprocessed using the Savitzky-Golay convolution derivative method, which was employed for subsequent spectral feature wavelength extraction and modeling. The characteristic wavelengths were extracted using competitive adaptive reweighted sampling (CARS), successive projections algorithm (SPA), and uninformative variable elimination combined with SPA (UVE-SPA). Conventional machine learning methods − support vector machine (SVM) and different deep learning models, including multilayer perceptron (MLP), mobile network version 2 (MobileNetV2), and residual neural network (ResNet), were studied and compared. The experiment showed that deep learning algorithms outperform traditional spectral analysis models in terms of classification performance. Furthermore, conducting feature wavelength extraction before constructing the classification model could reduce the model’s testing time and even improve its classification performance. Finally, the four models with better classification performance were validated using a validation set, and the combination of MobileNetV2 model UVE-SPA was selected as the optimized model for ducklings’ gender determination, with a classification accuracy of 98.3 % and an average validation time of 1.1 ms. In summary, the detection model established using near-infrared spectroscopy and MobileNetV2 can achieve non-destructive identification of the gender of ducklings. The findings can provide a preliminary research foundation and technical support for the subsequent design of related online intelligent detection systems.

Revealing motor insensitivity to food in Anorexia Nervosa as a potential mechanism contributing to calorie restriction: A mobile Approach Avoidance Task study

A change in implicit behavioural tendencies toward foods may contribute to the maintenance of calorie restriction in Anorexia Nervosa (AN). To test this hypothesis, we assessed approach-avoidance tendencies toward different categories of stimuli using a novel mobile version of the approach-avoidance task (AAT). The sample included 66 patients with restrictive AN and 84 healthy controls, all females. All participants performed the AAT in which they were required to approach or avoid stimuli (high-calorie foods, low-calorie foods, and neutral objects) by respectively pulling their phone towards themselves of pushing it away. Both the response time and the force of each movement were collected by means of the smartphone's accelerometer. The results revealed that patients with AN had a reduced tendency to approach food stimuli compared to healthy controls, who instead presented faster and stronger movements in approaching rather than avoiding foods as compared to neutral objects. This finding was particularly pronounced in patients with greater levels of malnutrition. No differences were instead observed comparing high-calorie and low-calorie foods. The observed reduction in the natural tendency to approach food stimuli is consistent with patients' eating behaviour and may contribute to the maintenance of calorie restriction, thus representing a possible target for novel therapeutic approaches.

How expansion to the Nintendo Switch impacts PC players’ game usage and spending: A study of an omni-channel strategy

Offering multiple retail channels for browsing and purchasing—an omni-channel strategy—is a well-established approach for modern retailers. This strategy is also increasingly adopted by ‘online-first' digital services such as social media and video gaming to expand consumer reach and enhance customer engagement. However, unlike the potential complementary relationships between physical and digital channels, it is unclear whether a firm’s channel expansion within the digital area (e.g., online to mobile) benefits firms or merely redistributes existing demand without growth. Using the context of a major online video game, we assess whether creating a mobile console version of an existing PC-based game causes meaningful behavioral changes among existing users. We find that mobile console adoption significantly impacts mobile channel adopters’ engagement, with a 31% increase in games played and a 6.9% increase in voluntary spending. Further analysis reveals that mobile console adopters enjoy the game over a broader range of hours, suggesting increased (ubiquitous) access is the mechanism behind this positive impact. Additionally, mobile adopters make more frequent purchases, although they do not necessarily spend more per purchase. We also observe that the impact of the mobile game is more pronounced among players at high risk of churning and those with sparse voluntary spending. Finally, our analysis shows that new mobile players experience a slight but significant dip in in-game performance. This finding suggests a need for game developers to help players mitigate the downside risk of transitioning between two distinct user environments.

A mobile telehealth program for behavioral treatment of urinary incontinence in women Veterans: Qualitative evaluation of MyHealtheBladder

Women Veterans constitute a distinctive cohort whose exposure to military service can contribute to development of bladder conditions, such as urinary incontinence (UI), as they age. Behavioral therapies are recommended as first-line treatment for incontinence, yet many VA Medical Centers do not have staff trained to administer them. The purpose of this research study was to conduct a qualitative program evaluation of MyHealtheBladder, a mobile telehealth version of an evidence-based eight‐week behavioral treatment program designed for women Veterans with incontinence. MyHealtheBladder uses mobile telehealth technology to teach pelvic floor muscle exercises, bladder control strategies, fluid management, risk factor reduction, and self‐monitoring. Eighteen women Veterans who completed a pilot study of MyHealtheBladder participated in semi-structured telephone interviews exploring their experience with the program. A directed content analysis was conducted of the transcribed interview data. Participants described ease of accessing MyHealtheBladder using smart phones and other mobile devices, emphasizing the flexibility of using the program at home, work, or while traveling. Most participants described program content as understandable, relevant, and easy to follow. They discussed how the program increased knowledge of UI, promoted consistency in practicing behavioral therapy, strengthened pelvic floor muscles, reduced urine leakage, and improved psychosocial wellbeing. Suggestions for improvement included more interaction with staff, more individualized tailoring of content to UI type, incorporating in-person clinic visits, and including supplementary material. Participants uniformly endorsed the program and recommended it for other women Veterans, as well as for those in active duty to prevent or treat UI earlier in the life course.

Improving preparation in the emergency trauma room: the development and impact of real-time data transfer and dashboard visualization system.

This study examines, with clinical end users, the features of a visualization system in transmitting real-time patient data from the ambulance to the emergency trauma room (ETR) to determine if the real-time data provides the basis for more informed and timely interventions in the ETR before and after patient arrival. We conducted a qualitative in-depth interview study with 32 physicians in six German and Swiss hospitals. A visualization system was developed as prototype to display the transfer of patient data, and it serves as a basis for evaluation by the participating physicians. The prototype demonstrated the potential benefits of improving workflow within the ETR by providing critical patient information in real-time. Physicians highlighted the importance of features such as the ABCDE scheme and vital signs that directly impact patient care. Configurable and mobile versions of the prototype were suggested to meet the specific needs of each clinic or specialist, allowing for the transfer of only essential information. The results highlight on the one hand the potential need for adaptable interfaces in medical communication technologies that balance efficiency with minimizing additional workload for emergency medical services and show that the use of pre-notification systems in communication between ambulance and hospital can be supportive. Further research is recommended to assess practical application and support in clinical practice, including a re-evaluation of the enhanced prototype by professionals.

DEVELOPMENT OF A SOFTWARE SYSTEM FOR SEARCHING FOR LOST ITEMS

The article presents an approach to developing a software system to facilitate the efficient search for lost items. As part of the study, the authors designed an integrated system that includes server, web, and mobile versions, which provides broad opportunities for identifying and returning lost property. In large urban agglomerations, the loss of personal items becomes a common problem. Existing solutions are often limited to preventive measures and do not provide sufficient support after the item’s loss. The lack of an effective feedback and identification system complicates the lost property search process. The developed system uses modern technologies such as Django for the backend, JavaScript for the web interface, and Flutter for creating cross-platform mobile applications. This approach makes it possible to expand the list of system users to the maximum extent. Django, a capable web framework, facilitates reliable data management and integration with various interfaces. The study involved the development of a database to provide storage and processing of all the necessary information. Using REST API ensured efficient interaction between the system’s server, web, and mobile parts. This approach allows different system components to exchange data in a unified format. The system lets users register individuals and legal entities, which makes it possible to use it in a wide range of public spaces. It helps to effectively search for and return lost items on the street and in public places, including restaurants, theatres, and transport hubs where lost items often occur. The software system created in this study addresses the critical problem of losing personal items. Widespread use of this system across various sectors could dramatically improve managing lost and found operations, turning a typically disorganised and ineffective process into an efficient, technology-driven one. The system’s implementation has the potential to significantly reduce the time and resources spent on searching for lost property and increase the productivity of lost property offices. Keywords: software system, item search, location, lost property office.

"An app is just available at all times"-the process and outcomes of converting the Georgia Tuberculosis Reference Guide into a mobile application.

The physical, paper-based Georgia TB Reference Guide has served as the clinical reference handbook on tuberculosis (TB) diagnostic and treatment guidelines for the state of Georgia in the United States. Supported by the Georgia Department of Public Health, the production of the 112-page palm-sized booklet was previously led by a team of Georgia-based TB experts at Emory University and printed every three-five years with updates to clinical management guidelines and TB consult contact information. However, the costs associated with editorial printing combined with delays in updating a static printed booklet with revised guidance hampered the utility of the tool. Considering the barriers with paper-based production and based on the beneficial use of apps to support the dissemination of clinical management guidance in other settings, the booklet was converted into a mobile application. This paper describes the process of developing a mobile app version of the Georgia TB Reference Guide in an easy-to-update and readily available format. We employed a user-centered design approach to develop the app, including a series of qualitative interviews and quantitative surveys. Participants included a mix of state officials and local TB experts. First, initial foundational interviews were conducted to conceptualize current utilization practices of both the paper and PDF versions of the tool. Second, the findings from the initial interviews were organized thematically and informed the design of the app, which was then beta tested by a round of previously unsampled TB experts as well as a re-sample from the initial interviews. Third, the designs were coded into developmental phases and beta tested among users of the current Georgia TB Reference Guide. Fourth, the app was published and downloaded by a pre-selected group of local users who provided answers to a follow-up survey after using the app for one month. Fifth, user growth, self-reported demographics, and app usage between February and July 2022 were recorded through automatic data metrics built into the app. The paper copy Georgia TB Reference Guide usage themes included commonly referenced content, navigation paths, and desired features and content. The themes were converted into features and designs such as prioritizing commonly reviewed topics and guide customization with bookmarks and notes. Iterations of the designs were driven by feedback from TB experts and included home page featured content, improving content readability, and improving the search feature. The follow-up survey revealed a 90% preference for the app over the paper version of the guide. In the six months following the app's release, the app was downloaded by 281 individuals in the United States. The majority of downloads were in Georgia and the app also expanded organically to 19 other states. The experience of converting the Georgia TB Reference Guide offers specific and effective steps to converting a medical reference guide into a mobile application tool that is readily available, easy to use, and easy to update. The organic dissemination of the app beyond the state of Georgia's borders within the first six months of app launch underscores desire among TB healthcare professionals for high-quality digital reference content outside the state. This experience offers clear outlines for replication in other contexts and demonstrates the utility of similar mobile medical reference tools.

Drivers of loyalty and consumer satisfaction with shearing urban mobility services: Carsharing, ridesharing, bikesharing, and kicksharing

Aim. To identify drivers of loyalty and consumer satisfaction with urban mobility shearing services.Objectives. To determine the characteristics of the use of shearing services; to formulate issues for shearing services that require priority attention; to identify drivers of loyalty and barriers to the use of shearing services, as well as drivers of user satisfaction with shearing services; to formulate recommendations for the development of the quality of shearing services.Methods. The authors applied the method of sociological survey (with participation of 615 respondents who use urban mobility sharing services at least once a year). The NPS index was used to identify drivers of loyalty, CSI index was used to detect drivers of customer satisfaction. The study was conducted in the context of such sharing services as carsharing, ridesharing, bikesharing and kicksharing, taking into account the relevant specific determinants of the quality of sharing services. The results were processed using general scientific methods of analysis and synthesis of information. Results. Users are loyal to carsharing, bikesharing and kicksharing, but not loyal to ridesharing. However, they are satisfied with ridesharing services in all four segments. The main drivers of loyalty were the convenience of using the services as an alternative to public transportation and the relative cheapness of the service. Respondents consider safety issues to be the main barrier. To a greater extent, consumers are satisfied with the technical side of the use of sharing services (we are talking about the convenience of the mobile application, confidentiality of personal data, technical condition of the car). Consumers are less satisfied with the speed of registration, loyalty programs, and the cost of insurance.Conclusions. Due to the fact that users are not loyal to ridesharing, operators of these services should primarily pay attention to safety during the trip, social capital of drivers (rating system), as well as the variety and number of available routes. In general, the area of growth of competitiveness of the shearing services on transport can be traced in the improvement of product metrics of web and mobile versions of applications, development of loyalty programs and pricing of insurance products

ImageAssist: A Novel Smartphone Application for Standardized Clinical Photography That Implements and Automates American Society of Plastic Surgery/Plastic Surgery Foundation Photographic Guidelines With Background Deletion.

Standardized medical photography of the face is a vital part of patient documentation, clinical evaluation, and scholarly dissemination. Because digital photography is a mainstay in clinical care, there is a critical need for an easy-to-use mobile device application that could assist users in taking a standardized clinical photograph. ImageAssist was developed to answer this need. The mobile application is integrated into the electronic medical record (EMR); it implements and automates American Society of Plastic Surgery/Plastic Surgery Research Foundation photographic guidelines with background deletion. A team consisting of a craniofacial plastic surgeon and the Health Information Technology product group developed and implemented the pilot application of ImageAssist. The application launches directly from patients' chart in the mobile version of the EMR, EPIC Haiku (Verona, Wisconsin). Standard views of the face (90-degree, oblique left and right, front and basal view) were built into digital templates and are user selected. Red digital frames overlay the patients' face on the screen and turn green once standardized alignment is achieved, prompting the user to capture. The background is then digitally subtracted to a standard blue, and the photograph is not stored on the user's phone. ImageAssist initial beta user group was limited to 13 providers across dermatology, ENT, and plastic surgery. A mix of physicians, advanced practice providers, and nurses was included to pilot the application in the outpatient clinic setting using Image Assist on their smart phone. After using the app, an internal survey was used to gain feedback on the user experience. In the first 2 years of use, 31 users have taken more than 3400 photographs in more than 800 clinical encounters. Since initial release, automated background deletion also has been functional for any anatomic area. ImageAssist is a novel smartphone application that standardizes clinical photography and integrated into the EMR, which could save both time and expense for clinicians seeking to take consistent clinical images. Future steps include continued refinement of current image capture functionality and development of a stand-alone mobile device application.

Mobile version of the Battery for the Assessment of Auditory Sensorimotor and Timing Abilities (BAASTA): Implementation and adult norms.

Timing and rhythm abilities are complex and multidimensional skills that are highly widespread in the general population. This complexity can be partly captured by the Battery for the Assessment of Auditory Sensorimotor and Timing Abilities (BAASTA). The battery, consisting of four perceptual and five sensorimotor tests (finger-tapping), has been used in healthy adults and in clinical populations (e.g., Parkinson's disease, ADHD, developmental dyslexia, stuttering), and shows sensitivity to individual differences and impairment. However, major limitations for the generalized use of this tool are the lack of reliable and standardized norms and of a version of the battery that can be used outside the lab. To circumvent these caveats, we put forward a new version of BAASTA on a tablet device capable of ensuring lab-equivalent measurements of timing and rhythm abilities. We present normative data obtained with this version of BAASTA from over 100 healthy adults between the ages of 18 and 87 years in a test-retest protocol. Moreover, we propose a new composite score to summarize beat-based rhythm capacities, the Beat Tracking Index (BTI), with close to excellent test-retest reliability. BTI derives from two BAASTA tests (beat alignment, paced tapping), and offers a swift and practical way of measuring rhythmic abilities when research imposes strong time constraints. This mobile BAASTA implementation is more inclusive and far-reaching, while opening new possibilities for reliable remote testing of rhythmic abilities by leveraging accessible and cost-efficient technologies.

Experience of correction of enzyme therapy in children with cystic fibrosis using computer systems and means of network communication

Justification. In recent years, great progress in the treatment of cystic fibrosis has been associated with the use of pathogenetic therapy (since 2012 - in world practice, since 2020 in the Russian Federation). Against the background of the use of which the nutritional status, the functional state of the lungs improves, but there is no complete restoration of the impaired functions of the organs, in particular, the external secretory function of the pancreas is restored only in young children with the timely appointment of targeted therapy The purpose of the study: to increase the effectiveness of correction of enzyme replacement therapy by an individualized approach. Methods. 140 children (boys - 81, girls - 59) with MV aged from 1 year to 18 years (average age 12.9±4.8 years) were examined. The study was conducted in 2022 in the Department of Cystic Fibrosis Scientific and «Research Clinical Institute of Childhood of the Ministry of Health of the Moscow Region» (clinical base of the scientific and clinical Department of Cystic fibrosis Research Center for Medical Genetic). Inclusion criteria - diagnosis of cystic fibrosis, chronic pancreatic insufficiency, severe. Exclusion criteria - short bowel syndrome, exacerbation of the disease. The doses of pancreatin per day were evaluated using the calculation method: units/g of fat in food and intestinal syndrome before and after correction using an algorithm of an individualized approach to calculating enzyme therapy. The observation period is 3 months Design: single-center, prospective, comparative Results. The study showed that the majority of 82 patients (59%) in the general group received less than 2000 U/g of fat, which is less than the reference values (2000-4000 U/g). The median daily dose was 1500 U / g of fat, which can be attributed to the peculiarities of dosing and the need for pancreatin in the Russian pediatric population of patients with cystic fibrosis. The results are consistent with the data of recent studies indicating an acceptable dosage range of pancreatin 1000-4000 units / g of fat in food. In the course of the study, an algorithm for individualized correction of enzyme replacement therapy was developed and the effectiveness of this approach was shown. Conclusion. When calculating pancreatin for the fat content in food, the dose was below the recommended values of 2000-4000 units / g and amounted to 1500 units / g, which indicated that it did not meet the needs of children in enzymes and required individual correction. This served as the basis for the development of an algorithm for individualized correction of enzyme replacement therapy. The effectiveness of this approach using computer technology (inpatient program for doctors and mobile version for patients), in the form of reduction / relief of intestinal syndrome, is shown. To increase compliance and to train parents to control diet and enzyme replacement therapy, it is advisable to use computer programs and mobile applications to calculate the diet and dosage of pancreatin for each meal.

Early detection of sweet potato weevil (Cylas formicarius) and scab diseases (Sphaceloma batatas) outbreak based on android application

Sweet potato weevil and scab disease are major pests and diseases that become obstacles for increasing sweet potato production in Indonesia. Recently, the incidence of both pest and disease attacks can be detected earlier by using an android-based mobile application. This study aims to assemble an android-based mobile application for early detection of the outbreak of sweet potato weevil and scab disease. This research was conducted in in Malang Regency, East Java, from September to December 2022. Research was carried out by survey, observation, literature studies, and interview with the leaders of farmer association, sweet potato farmers, and local agricultural extension staff. All basic data and supporting data as a trigger for the occurrence of the weevil and scab disease have been collected from the several sample areas. The information was arranged in clusters according to the priority of each variable then was entered into the android studio. The user must enter the supporting data based on the application program to find out the percentage of sweet potato weevil and scab disease. Understanding the predictive value of the incidence of major pests and diseases is required, so farmers can anticipate earlier and prepare appropriate, effective and efficient control technology. An-android mobile application version 1 for early detection of pest and disease which was successfully assembled was expected to be greatly assist sweet potato farmers for maintain their cultivation from yield losses due to C. formicarius and scab which can reduce the quantity and quality by up to 100%.

Such a model became the basis for using object-oriented programming methods to obtain a full-fledged multi-user information system. Graphic images of screens of mobile and web-oriented versions of the system with a description of the functionality of user categories are presented. The developed information system allows to systematize and unify fishery processes, provide state control of the industry, and attract monetary investments into the industry.

On the Complexity of the Web’s PKI: Evaluating Certificate Validation of Mobile Browsers

Digital certificates are frequently used to secure communications between users and web servers. Critical to the Web's PKI is the secure validation of digital certificates. Nonetheless, certificate validation itself is complex and error-prone. Moreover, it is also undermined by particular constraints of mobile browsers. However, these issues have long been overlooked. In this paper, we undertook the first systematic and large-scale study of the certificate validation mechanism within popular mobile browsers to highlight the necessity of reassessing it among all released browsers. To this end, we first compile a comprehensive test suite to identify security flaws in certificate validation from various aspects. By designing and implementing a generic, automated testing pipeline, we effectively evaluate 30 popular browsers on two mobile OS versions and compare them with five representative desktop browsers. We found the latest mobile browsers Accept as many as 33.2% invalid certificates and Reject merely 5.4% invalid ones on average, leaving the majority of them to be decided by users who usually have little expertise. Our findings shed light on the severity and inconsistency of certificate validation flaws across mobile browsers, which are likely to expose users to MITM attacks, spoofing attacks, and so forth.
