Abstract
BackgroundA review of the literature on iron treatments for iron-deficient anaemia in pregnancy indicated duplication of baseline and outcome tables in two separate randomised controlled trials (RCTs) that share only a single author. AimTo assess the integrity of randomised clinical trials from Dr A.M. Darwish, Assiut University, Egypt. DesignAssessment of Research Integrity. MethodsWe tabulated the characteristics of studies, compared baseline and outcome tables between articles and looked for implausible findings. We used the distribution of baseline p-values to assess whether the summary statistics of baseline characteristics were consistent with properly conducted randomisation. ResultsWe identified 14 RCTs (1,405 participants) published between October 2004 and September 2019. Two pairs of studies showed considerable similarities in baseline characteristics, while another pair of studies was plagiarized. The analysis of baseline p-values indicated a low probability that all the studies featured randomised treatment allocation. ConclusionOur analysis of the RCTs of Dr Darwish suggests possible integrity problems. We recommend a critical investigation of the studies that have not been retracted. Until that has been completed, these studies should not be used to inform clinical practice.
