Randomised controlled trials (RCTs) are one of the most important tools to estimate effects of medical interventions. However, there are a number of issues relating to the statistical analysis of RCTs over which there is much debate. We aim to consider and raise discussion of a number of these issues, and suggest possible statistical approaches for dealing with these in the analyses of RCTs. We briefly introduce here some of these issues.


  • Cluster randomised trials
  • Covariate adjustment
  • Subgroup analysis
  • Missing data
  • Non-compliance
  • Sequential trials
  • Good practice in trials
