Evidence of publication bias in multiple sclerosis clinical trials: a comparative analysis of published and unpublished studies registered in ClinicalTrials.gov.
Complete and timely publication of clinical trials ensures that patients and the medical community are fully informed when making treatment decisions. The aim of this study is to assess the publication of phase III and IV clinical trials on multiple sclerosis (MS) drugs that have been carried out between 2010 and 2019 and to identify the factors associated with their publication in peer-reviewed journals. ⋯ Phase III and IV clinical trials on MS drugs are prone to under-reporting and publication bias. Efforts must be made to promote a complete and accurate dissemination of data in MS clinical research.
