It's almost time for the Christmas edition of the BMJ to hit your doormats, and in this festive edition of Talk Evidence we're going to be talking Christmas research. Joining Helen and Juan, we have Tim Feeney, BMJ research editor and researcher into Surgical outcomes at Boston University.

In this episode we'll be hearing about the health of footballers, and if a career in the sport predisposes Swedish players to substance use disorders. We'll hear about the performance of BMJ’s editors, when it comes to assessing the impact of a paper. We'll find out if AI algorithms can pass UK radiology exams, misinformation and a belief that everything causes cancer, and finally, some tips from BMJ’s statisticians to set the world right
