Unexplained discrepancies were most common for the analysis model (n = 31, 35%) and analysis population (n = 28, 31%), followed by the use of covariates (n = 23, 26%) and the approach for handling missing data (n = 16, 18%). Many protocols or statistical analysis plans were dated after the trial had begun, so earlier discrepancies may have been missed. Conclusions Unexplained discrepancies in the statistical methods of randomised trials are common. Increased transparency is required for proper evaluation of results.Background
