Rare adverse events in clinical trials: understanding the rule of three
Investigators should report rare and very rare adverse events in clinical trials: Igho Onakpoya reports why it is important that all events are reported irrespective of their frequency. Even though they may not give a signal in any single trial, a meta-analysis could reveal potentially important drug-adverse event associations that might require further […]
Why do rates of knee arthroscopy differ?

Controversies in PSA screening
40 years after its discovery, a re-analysis of the two largest trials to date, controversially suggests PSA screening may actually be beneficial.

PSA […]

In some areas, such as the treatment of illicit […]
