The methodological and practical concerns of conducting an integrated bio-behavioural survey with female sex workers:

BACKGROUND
 Globally, HIV prevalence among female sex workers (FSWs) is higher than in the general population, makingHIV research among FSWs an important undertaking. However, due to the stigma associated with sexwork, FSWs are a hidden population difficult to engage in research studies. This formative research studyconsidered methodological practices that were acceptable and suitable to FSWs and that would ensure optimalparticipation in the South African Health Monitoring Study (SAHMS), an integrated biological-behaviouralsurvey (IBBS).
 METHODS
 The study was conducted in Durban, Johannesburg and Cape Town in 2013. Through purposive sampling, 91FSWs participated in focus group discussions. Twenty-one researchers and stakeholders working closely withFSWs and FSWs themselves participated in in-depth interviews. Data was collected using a semi-structuredqualitative interview guide.
 RESULTS
 Respondent-driven sampling was cited as the preferred recruitment method. Participants providedrecommendations on IBBS study procedures, study logistics and the disposition of study staff. The majority ofparticipants were confident that FSWs enrolled in IBBS would be willing to test for HIV, as well as accept theuse of biometrics and laptops. Participants’ concerns about confidentiality and study staff attitudes were citedas common barriers to participation.
 CONCLUSION
 Participation of FSWs in an IBBS is important to determine HIV prevalence and inform preventionstrategies. Using a participatory approach to engage FSWs in research studies can help ensure ethicalresearch implementation, inform methodological best practices and increase recruitment and participation.Including FSWs in the planning and implementation of surveys can contribute to their sense of communityempowerment.

A cross-sectional investigation into the occupational and socio-demographic characteristics of British police force employees reporting a dietary pattern associated with cardiometabolic risk: findings from the Airwave Health Monitoring Study

PurposeThe aims of this study were to (1) determine the association between diet quality using the Dietary Approaches to Stop Hypertension (DASH) score and cardiometabolic risk in a British working population and (2) identify employee characteristics associated with reporting a poorer quality dietary pattern.MethodsBritish police employees enrolled (2007–2012) into the Airwave Health Monitoring Study (n = 5527) were included for sex-specific cross-sectional analyses. Dietary intakes were measured using 7-day food records. DASH score was calculated to determine diet quality. Logistic regression evaluated associations between (1) diet quality and increased cardiometabolic risk (defined as ≥ 3 risk markers: dyslipidaemia, elevated blood pressure, waist circumference, CRP or HbA1c), and (2) poor diet quality (lowest fifth of DASH score distribution) and employee characteristics.ResultsEmployees recording a poor diet quality had greater odds (OR) of increased cardiometabolic risk independent of established risk factors (demographic, lifestyle and occupational) and BMI: men OR 1.50 (95% CI 1.12–2.00), women: OR 1.84 (95% CI 1.19–2.97) compared to the healthiest diet group. Characteristics associated with reporting a poor quality diet were employment in Scotland vs. England: men OR 1.88 (95% CI 1.53–2.32), women: OR 1.49 (95% CI 1.11–2.00), longer working hours (≥ 49 vs. ≤40 h) men: OR 1.53 (95% CI 1.21–1.92) women: OR 1.53 (95% CI 1.12–2.09). For men, job strain (high vs. low) was associated with reporting a poor diet quality OR 1.66 (95% CI 1.30–2.12).ConclusionsThe general population disparities in diet quality between England and Scotland were reflected in British police employees. The association of longer working hours and job strain with diet quality supports the targeting of workplace nutritional interventions.

Monitoring the Damage State of Fiber Reinforced Composites Using an FBG Network for Failure Prediction.

A structural health monitoring (SHM) study of biaxial glass fibre-reinforced epoxy matrix composites under a constant, high strain uniaxial fatigue loading is performed using fibre Bragg grating (FBG) optical sensors embedded in composites at various locations to monitor the evolution of local strains, thereby understanding the damage mechanisms. Concurrently, the temperature changes of the samples during the fatigue test have also been monitored at the same locations. Close to fracture, significant variations in local temperatures and strains are observed, and it is shown that the variations in temperature and strain can be used to predict imminent fracture. It is noted that the latter information cannot be obtained using external strain gages, which underlines the importance of the tracking of local strains internally.

Successful nutrition policy: improvement of vitamin D intake and status in Finnish adults over the last decade

Due to vitamin D intake below recommendation (10 µg/day) and low (<50 nmol/l) serum 25-hydroxycholecalciferol (25(OH)D) concentration in Finnish population, the fortification of liquid dairy products with 0.5 µg vitamin D/100 g and fat spreads with 10 µg/100 g started in Finland in December 2002. In 2010, the fortification recommendation was doubled. The aim of this study was to investigate whether the vitamin D intake and status have improved among Finnish adults as a consequence of these nutrition policy actions. A further aim was to study the impact of vitamin supplement use to the total vitamin D intake. A cross-sectional survey was conducted every 5 years. The National FINDIET Survey was conducted in Finland as part of the National FINRISK health monitoring study. Dietary data were collected by using a computer-assisted 48-h dietary recall. In 2002, dietary data comprised 2007, in 2007, 1575 and 2012, 1295 working aged (25-64 years) Finns. The mean D-vitamin intake increased from 5 µg/day to 17 µg/day in men and from 3 µg/day to 18 µg/day in women from 2002 to 2012. The most important food sources of vitamin D were milk products, fat spreads and fish dishes. The share of milk products was 39% among younger men and 38% among younger women, and 29% among older men and 28% among older women. Fat spreads covered on average 28% of vitamin D intake, except for younger men for which it covered 23%. Fish dishes provided 28% of vitamin D intake for older men and women, and approximately 18% for younger ones. In January-April 2012, the average serum 25-hydroxycholecalciferol (25(OH)D) concentration for men was 63 nmol/l for men and for women 67 nmol/l for women. The fortification of commonly used foods with vitamin D and vitamin D supplementation seems to be an efficient way to increase the vitamin D intake and the vitamin D status in the adult population.

Validation of objective records and misreporting of personal radio use in a cohort of British Police forces (the Airwave Health Monitoring Study)

BackgroundTerrestrial Trunked Radio (TETRA) is a digital communication system progressively adopted by Police Forces in Great Britain since 2001. In 2000, the UK Independent Expert Group on Mobile Phones suggested that exposure to TETRA-like signal modulation might have adverse effects on health. The Airwave Health Monitoring Study was established to investigate possible long-term effects of TETRA use on health. This requires estimation of TETRA use among Police Force employees participating in the study. MethodsWe investigated TETRA usage among 42,112 Police officers and staff. An algorithm was created to link each personal radio user to his/her objective radio usage records for the 26,035 participants with available data. We linked 16,577 personal radio users to their objective radio usage records and compared self-reported usage with data from the TETRA operator for those individuals. ResultsFor weekly usage, the correlation between self-reported and operator-derived personal radio usage was r=0.69 for number and r=0.59 for the duration of calls. Compared with objective data, participants under-reported the number of calls and over-reported the duration of calls by a factor of around 4 and 1.6 respectively. Correlations were lower and bias higher when looking at daily usage. ConclusionWhere both objective and self-reported information were available, our study showed substantial misreporting in self-reported TETRA usage. Successful linkage of large numbers of TETRA users to objective data on their personal radios will allow objective assessment of TETRA radio usage for these participants and development of algorithms to correct bias in self-reported data for the remainder.

Family characteristics and health behaviour as antecedents of school nurses’ concerns about adolescents’ health and development: A path model approach

BackgroundFamily socio-economic factors and parents’ health behaviours have been shown to have an impact on the health and well-being of children and adolescents. Family characteristics have also been associated with school nurses’ concerns, which arose during health examinations, about children's and adolescents’ physical health and psychosocial development. Parental smoking has also been associated with smoking in adolescents. ObjectivesThe aim of this study was to determine to what extent school nurses’ concerns about adolescents’ physical health and psychosocial development related to family characteristics are mediated through parents’ and adolescents’ own health behaviours (smoking). DesignA path model approach using cross-sectional data was used. SettingsIn 2008–2009, information about health and well-being of adolescents was gathered at health examinations of the Children's Health Monitoring Study. ParticipantsAltogether 1006 eighth and ninth grade pupils in Finland participated in the study. MethodsThe associations between family characteristics, smoking among parents and adolescents and school nurses’ concerns about adolescents’ physical health and psychosocial development were examined using a structural equation model. ResultsPaternal education had a direct, and, through fathers’ and boys’ smoking, an indirect association with school nurses’ concerns about the physical health of boys. Paternal labour market status and family income were only indirectly associated with concerns about the physical health of boys by having an effect on boys’ smoking through paternal smoking, and a further indirect effect on concerns about boys’ health. In girls, only having a single mother was strongly associated with school nurses’ concerns about psychosocial development through maternal and adolescent girl smoking. ConclusionsSocio-economic family characteristics and parental smoking influence adolescent smoking and are associated with school nurses’ concerns about adolescents’ physical health and psychosocial development. The findings underline the importance of comprehensively taking into account adolescents’ and parents’ health behaviours and the family situation in health-care contacts when providing health counselling.

An integrated approach for structural health monitoring using an in-house built fiber optic system and non-parametric data analysis

Multivariate statistics based damage detection algorithms employed in conjunction with novel sensing technologies are attracting more attention for long term Structural Health Monitoring of civil infrastructure. In this study, two practical data driven methods are investigated utilizing strain data captured from a 4-span bridge model by Fiber Bragg Grating (FBG) sensors as part of a bridge health monitoring study. The most common and critical bridge damage scenarios were simulated on the representative bridge model equipped with FBG sensors. A high speed FBG interrogator system is developed by the authors to collect the strain responses under moving vehicle loads using FBG sensors. Two data driven methods, Moving Principal Component Analysis (MPCA) and Moving Cross Correlation Analysis (MCCA), are coded and implemented to handle and process the large amount of data. The efficiency of the SHM system with FBG sensors, MPCA and MCCA methods for detecting and localizing damage is explored with several experiments. Based on the findings presented in this paper, the MPCA and MCCA coupled with FBG sensors can be deemed to deliver promising results to detect both local and global damage implemented on the bridge structure.

The Airwave Health Monitoring Study of police officers and staff in Great Britain: Rationale, design and methods

BackgroundThe Airwave Health Monitoring Study was established to evaluate possible health risks associated with use of TETRA, a digital communication system used by police forces and other emergency services in Great Britain since 2001. The study has been broadened to investigate more generally the health of the work force. MethodsFrom 2004, participants from each force who agreed to participate were enrolled either with an enrolment questionnaire or a comprehensive health screening performed locally. This includes questionnaire, 7-day food diaries, anthropometry, measurements of cardiovascular and cognitive function, blood chemistry, coagulation and haematology. Blood and urine samples are stored in vapour phase liquid nitrogen allowing long-term access for biochemical or genetic analysis. Access to the resource is via an access committee and a steering committee, including external scientific advisers as well as representatives of the police officers and staff. ResultsBy the end of 2012, the study had recruited 42,112 participants, of whom 35,199 (83.6%) had attended the health screening. Almost two thirds of participants were men and 71% of them were a TETRA user. Being in lower ranks (constable/sergeant and staff) was associated with a worse cardio-metabolic risk profile compared to higher ranks (inspector or chief inspector, superintendent and above). ConclusionThe Airwave Health Monitoring Study is the only large-scale cohort study of police employees worldwide. The specificities of this sample, such as its well-defined job hierarchy, make it a particularly valuable occupational cohort. Participants have consented to the use of their data and samples for future, currently unspecified, research purposes.

USE OF XYLAZINE HYDROCHLORIDE–KETAMINE HYDROCHLORIDE FOR IMMOBILIZATION OF INDIAN FOX (VULPES BENGALENSIS) IN FIELD SITUATIONS

Reports on doses of anesthetic agents for safe and effective immobilization of most wild species occurring in India are very limited. Further, the anesthetic agents available in India for field immobilizations are limited to xylazine hydrochloride and ketamine hydrochloride. A safe and effective dosage of xylazine-ketamine for Indian fox (Vulpes bengalensis) is reported, based on 37 wild Indian fox immobilizations between April 2006 and May 2007. Foxes captured for a radiotelemetry and health monitoring study were immobilized with a mixture of xylazine (2.27 +/- 0.44 mg/kg) and ketamine (13.39 +/- 2.26 mg/kg). Induction and recovery was smooth and uneventful in all foxes. The duration of anesthesia was sufficient for the fitting of radiotransmitters, morphometric measurements, and blood sampling. No life-threatening adverse effects of immobilization were documented for at least 1 mo postimmobilization. The results suggest that field immobilization of Indian foxes with 2 mg/kg xylazine and 13 mg/kg ketamine is effective and safe.

Body mass index and metabolic factors predict glomerular filtration rate and albuminuria over 20 years in a high-risk population

BackgroundThe number of individuals suffering from chronic kidney disease (CKD) is increasing. Therefore, early identification of modifiable predictors of CKD is highly desirable. Previous studies suggest an association between body mass index (BMI), metabolic factors and CKD.MethodsData of 241 high risk patients with information on renal function and albuminuria from the Renal Disease in Vorarlberg (RENVOR) study (2010–2011) were linked with long-term measurements of metabolic factors in the same patients from the population-based Vorarlberg Health Monitoring & Prevention Program (VHM&PP) cohort study (1988–2005). Actual estimated glomerular filtration rate (eGFR) and urinary albumin creatinine ratio (ACR) were determined. BMI, blood pressure, fasting glucose, total cholesterol, triglycerides and Gamma-glutamyltransferase (GGT) were available from previous health examinations performed up to 25 years ago. Linear regression models were applied to identify predictors of current renal function.ResultsAt all-time points BMI was significantly inversely associated with actual eGFR and positively with actual albuminuria in men, but not in women. Serum GGT and triglycerides were significantly positively associated with albuminuria in men at all-time points. Fasting glucose levels more than 20 years earlier were associated with increased albuminuria in women and reduced eGFR in men, whereas at later time points it was associated with albuminuria in men.ConclusionsBMI, serum GGT, and triglycerides are long-term predictors of renal function in men. In women however, anthropometric and metabolic parameters seem to be less predictive of eGFR and albuminuria.

Health monitoring of a historical monument in Jordan based on ambient vibration test

This paper summarizes the experimental vibration-based structural health monitoring study on a historical monument in Jordan. In this work, and within the framework of the European Commission funded project "wide-Range Non-Intrusive Devices Toward Conservation of Historical Monuments in the Mediterranean Area", a seven and a half century old minaret located in Ajloun (73 km north of the capital Amman) is studied. Because of their cultural value, touristic importance and the desire to preserve them for the future, only non-destructive tests were allowed for the experimental investigation of such heritage structures. Therefore, after dimensional measurements and determination of the current state of damage in the selected monument, ambient vibration tests are conducted to measure the accelerations at strategic locations of the system. Output-only modal identification technique is applied to extract the modal parameters such as natural frequencies and mode shapes. A Non-linear version of SAP 2000 computer program is used to develop a three-dimensional finite element model of the minaret. The developed numerical model is then updated according to the modal parameters obtained experimentally by the ambient-vibration test-results and the measured characteristics of old stone and deteriorated mortar. Moreover, a parametric identification method using the N4Sid state space model is employed to model the dynamic behavior of the minaret and to build up a robust, immune and noise tolerant model.

Is Serum Gamma-Glutamyltransferase a Biomarker of Xenobiotics, Which Are Conjugated by Glutathione?

A meta-analysis of 10 prospective cohort studies,1 including our own,2 reported that serum γ-glutamyltransferase (GGT) predicted incident vascular events. This meta-analysis posed one important, but unsolved question: why does serum GGT predict incident vascular events? In addition to vascular events, serum GGT predicts various important clinical outcomes including type 2 diabetes, metabolic syndrome, and renal problems.3–5 Serum GGT has traditionally been used as a marker of alcohol consumption; however, alcohol consumption cannot explain the disease relationships with serum GGT because these associations have been observed among nondrinkers as well as drinkers. The other prevailing interpretations are that serum GGT predicts clinical outcomes as a marker of nonalcoholic fatty liver disease (NAFLD) or oxidative stress.6–8 Although both of these explanations have some merit, each also has problems. Although not clearly stated in many of the reports,1–5 most associations of serum GGT with clinical outcomes were dose-response relations within the normal range of serum GGT; we submit that this aspect of the association is critical to interpretation. First, even though NAFLD may partially explain the associations among subjects with a relatively high serum GGT activity and NAFLD can present even among subjects with low normal serum GGT, NAFLD is unlikely to fully explain the graded associations with clinical outcomes which were observed among subjects with serum GGT in the low part of its normal range, less than 20 or 30 U/L. However, it is worthwhile to note that serum GGT may be a predictor of the future risk of NAFLD. In a prospective study by our group,9 serum GGT within its normal range strongly predicted the future risk of chronic elevation of serum alanine aminotransferase (ALT), but serum ALT within its normal range did not predict the future risk of chronic elevation of serum GGT. The …

Education, sense of mastery and mental health: results from a nation wide health monitoring study in Norway

BackgroundEarlier studies have shown that people with low level of education have increased rates of mental health problems. The aim of the present study is to investigate the association between level of education and psychological distress, and to explore to which extent the association is mediated by sense of mastery, and social variables like social support, negative life events, household income, employment and marital status.MethodsThe data for the study were obtained from the Level of Living Survey conducted by Statistics Norway in 2002. Data on psychological distress and psychosocial variables were gathered by a self-administered questionnaire, whereas socio-demographic data were based on register statistics. Psychological distress was measured by Hopkins Symptom Checklist 25 items.ResultsThere was a significant association between low level of education and psychological distress in both genders, the association being strongest in women aged 55–67 years. Low level of education was also significantly associated with low sense of mastery, low social support, many negative life events (only in men), low household income and unemployment,. Sense of mastery emerged as a strong mediating variable between level of education and psychological distress, whereas the other variables played a minor role when adjusting for sense of mastery.ConclusionLow sense of mastery seems to account for much of the association between low educational level and psychological distress, and should be an important target in mental health promotion for groups with low level of education.

Crack mapping in RC members using distributed coaxial cable crack sensors: modeling and application

The paper presents a model to calculate reinforcement strain using measured crack width in members under applied tension, flexure, and/or shear stress. Crack mapping using a new type of distributed coaxial cable sensors for health monitoring of large-scale civil engineering infrastructure was recently proposed and developed by the authors. This paper shows the results and performance of such sensors mounted on near surface of two flexural beams and a large scale reinforced concrete box girder that was subjected to cyclic combined shear and torsion. The main objectives of this health monitoring study was to correlate the sensor's response to strain in the member, and show that magnitude of the signal's reflection coefficient is related to increases in applied load, repeated cycles, cracking, and reinforcement yielding. The effect of multiple adjacent cracks, and signal loss was also investigated. The results shown in this paper are an important step in using the sensors for crack mapping and determining reinforcement strain for in-situ structures.

Current pediatric and maternal lead levels in blood and breast milk in Andean inhabitants of a lead-glazing enclave.

Prenatal and postnatal lead (Pb) exposure may induce neurodevelopmental disabilities in children. As part of an ongoing health-monitoring study, blood lead (PbB) levels were compared in 90 children tested in 2003 (current group) and 166 children tested between 1996 and 2000 (reference group) in Ecuadorian Andean villages with high Pb contamination. The mean PbB level for children in the reference group was 40 microg/dL (range, 6.2-119.1), and significantly higher than the mean PbB level of 25.5 microg/dL (range, 2.1-94.3) for the current group (t test, P = 0.0001). An analysis of variance revealed no significant main effects for age and gender and no significant interaction between age and gender for the current group but a significant age by gender interaction for the reference group (F = 5.96, P = 0.01). Regression analysis revealed a significant correlation (r = 0.258, P = 0.01) between PbB level and age for males but not for females in the reference group. The Pb levels in breast milk from nursing mothers ranged from 0.4-20.5 microg/L (mean, 4.6), and the PbB levels in the breastfeeding mothers ranged from 4.5-35.2 microg/dL (mean, 17.1). The PbB levels of mother-infant pairs ranged from 4.6-27.4 microg/dL for mothers and 3.9-33.5 microg/dL for infants. The results showed significantly reduced PbB levels in children in the study area and suggest that a Pb education and prevention program contributed to the current reduction in Pb intoxication.

An Evaluation of Changes in Tree Crown Characteristics to Assess Forest Health in Two Indiana State Parks

Abstract An evaluation of tree crown characteristics was conducted by means of a Forest Health Monitoring study in Turkey Run and Shades State Parks, Indiana. Crown dieback, foliage transparency, and crown density were summarized for three consecutive measurement years, and the short-term changes in these characteristics were quantified in an effort to identify potential forest health concerns. In both Shades and Turkey Run State Parks, no significant changes were detected in the levels of crown dieback and crown density. Only for Shades hardwoods, and more specifically hickory trees (Carya spp.), was there an unfavorable change in foliage transparency; however, this change did not appear extraordinary given the Forest Health Monitoring measurement quality objectives. This study demonstrated that given the current body of knowledge about the acceptable levels for the crown characteristics, the majority of trees in Shades and Turkey Run State Parks are not exhibiting responses to extreme stress and should be considered healthy.

Performance of smart piezoceramic patches inhealth monitoring of a RC bridge

This paper presents the results of a health monitoring study, carried outduring the destructive load testing of a prototype reinforced concrete (RC)bridge. The bridge was made up of cement-concrete reinforced with steel rods,and represented a popular class of road bridges in which regular healthmonitoring is a very important issue during the service life. The bridge wasinstrumented with piezoceramic transducer (PZT) patches, which wereelectrically excited at high frequencies, of the order of kHz, and the realpart of admittance (conductance) was extracted as a function of the excitingfrequency. The patches were scanned for the acquisition of this signature atvarious stages during the loading process. The signatures of the patcheslocated in the vicinity of the damage were found to have undergone drasticchanges, while those farther away were less affected. Damage wasquantified in non-parametric terms using the root mean square of the deviationin signatures with respect to the baseline signature of the healthy state.This non-parametric index was found to correlate well with the damageprogression in the structure.

Health Monitoring Of Civil Infrastructure Using Smart PiezoelectricTransducer Patches

In recent years, structural health monitoring has become an important requirement in Civil Engineering, especially in the densely populated areas such as many Asian cities. Various monitoring techniques have been proposed and studied. This paper will focus on the application of the piezoceramic transducer (PZT) patches on the health monitoring of civil infrastructure. The PZT patches, attached to the surface of the structure, are electrically excited, and real part of electrical admittance (conductance) is extracted as a function of the excitation frequency. An Impedance Analyzer is used to scan the patches over a certain range of frequency for the acquisition of the signature. The deviation of the signature from that recorded for the healthy state provides an indicator for the health of the structure. This technique is non-destructive in nature and the wide range of the excitation frequency (from a few Hz to a few MHz) enables this technique to capture structural damage from small to large scale. Specifically, the results of a health monitoring study, carried out during the destructive load testing of a prototype RC bridge, will be presented. The bridge was instrumented with the PZT patches, which were excited at high frequencies, of the order of kHz. The signatures of the patches located in the vicinity of the damages were found to have undergone drastic changes, while those farther away were only marginally affected, thus confirming the damage localization capability of the technique for large concrete structures. The damages were quantified in nonparametric terms using root mean square deviation in signatures with respect to the baseline signature of the healthy state.

Factors influencing recovery from and duration of lameness in Michigan (USA) horses

The objective of this study was to identify factors that may affect recovery from and duration of a case of lameness in a stratified random sample of Michigan horses. This was done using data from Phase-II of the Michigan equine monitoring system (MEMS Phase-II), the equine health-monitoring study [Kaneene et al., Prev. Vet. Med. 29 (1997b) 277–292; Ross and Kaneene, Prev. Vet. Med. 28 (1996a) 209–224; Ross and Kaneene, Prev. Vet. Med. 29 (1996b) 59–75; Ross et al., Am. J. Vet. Res. 59 (1997) 23–29]. In this study, statistical modelling was conducted to evaluate risk factors affecting recovery from and duration of lameness using multivariable logistic regression and Cox's proportional hazards regression, respectively. Of 357 incident lameness cases reported during MEMS Phase-II, 280 (78.6%) were reported to have recovered. The median duration of a lameness case was 18 days (1st quartile (Q): 1, maximum (Max): 360). A total of 296 of 357 (82.9%) incident lameness cases received some type of treatment. Of 619 total treatments used, 329 (53.2%) were administered, conducted or applied by a veterinarian. Horses experiencing other types of lameness were less likely to recover than those experiencing hoof lameness (odds ratio (OR) = 0.48; 95% CI: 0.25, 0.93). Horses that had participated in exercise-related activities during the study period and prior to the lameness were more likely to recover (OR = 1.91; 95% CI: 1.05, 3.50). Treatment of the lameness was associated with an increased likelihood of recovery (OR = 1.82; 95% CI: 0.97, 3.45). Cases with a veterinarian involved in the diagnosis were associated with a decreased risk of recovery (OR = 0.48; 95% CI: 0.27, 0.84) and a longer duration lameness (HR = 0.58; 95% CI: 0.45, 0.73)—which might indicate that these cases were more complex or severe. Although cases treated for lameness were more likely to recover (OR = 1.82; 95% CI: 1.05, 3.50), treatment was not associated with lameness duration (HR = 0.58; 95% CI: 0.45, 0.73).
