Safety Reporting in Randomized Clinical Trials A Need for Improvement

The reporting of adverse events (AEs) in randomized clinical trials (RCTs) is often lacking in the publication of trials. Part of the problem is the way safety data are reported in RCTs. Reporting of "time to event," use of standardized incidence ratios for comparison to normal population or disease controls, use of "patient years" when reporting AE, and adequate sample size and power calculations are some of the problems that need to be addressed and improved in RCTs.
