Understanding and Addressing Low Power in Clinical Trials

Gosh was I lucky to speak with Professor Erik Van Zwet from Leiden University in the Netherlands. He is the first author on a recent NEJM Evidence paper looking at more than 23,000 trials in the Cochrane Database. (I linked to an URL that should get by the paywall.)

There are technical aspects of this paper. We hit on some (not a lot) of them. The gist of it though is really important when we look at evidence. Erik did an excellent job of explaining P-values, trial power, and, at the end, we discuss how this work might inform the ability of trials to replicate.

This discussion also pairs well with one I had with computer scientist Ben Recht.

I hope you enjoy the conversation.
