This dataset contains individual-level participant data collected as part of the Methotrexate and Prednisolone Study (MaPs) in Erythema Nodosum Leprosum (ENL), a multicentre, double-blind, placebo-controlled randomised clinical trial conducted in Ethiopia, India, Indonesia and Nepal.
The trial evaluated the efficacy and safety of weekly oral methotrexate in combination with prednisolone compared with prednisolone alone for the treatment of ENL. The dataset includes demographic characteristics, clinical assessments, ENLIST ENL Severity Scale (EESS) scores, treatment allocation (de-identified), medication use, adverse events, laboratory results and health-related quality of life measures (Dermatology Life Quality Index [DLQI] and SF-36) collected during 60 weeks of follow-up.
The study has removed direct identifiers, such as names, to protect participant confidentiality. However, it is recognized that some measures may still pose a re-identification risk when combined with other sources. To balance participant confidentiality with research reproducibility and data sharing conditions, access to data is managed through a safeguarded application process. Researchers are asked to complete an application form, specifying the variables they wish to access. This list will be reviewed to assess re-identification risks and determine any necessary anonymisation measures, such as grouping ages, broadening dates, or redacting text. Where full anonymisation is not possible, researchers will be required to sign a Data Transfer Agreement (DTA) that sets out data security requirements before access is granted.
The dataset contains 90 variables in total, outlined below.
