This is data from a systematic review of the reporting of monitoring in protocol papers of randomised controlled trials (RCTs). The systematic review was conducted in April to June 2020 in seven journals that commonly publish clinical trial protocol papers, and in papers published by the BioMed Central publishing group. Data was extracted on each protocol paper published between 1st January and 31st May 2020. This dataset comprises information on the extent of the reporting of monitoring in each protocol paper.
