We’ve not done a critical appraisal nugget for a while now. No excuses, we’ve just been busy with other stuff, but we need to rectify that now. This week I sat down with Rick Body and talked through some of the issues around the use and abuse of p-values in research, and how that affects how we interpret them in critical appraisal.

Some useful links to stuff we’ve mentioned on the podcast.
