Episode 484: PREMIUM – Vitamin D for respiratory infections and overestimating diagnoses

In episode 484, Mike and James go PREMIUM on two topics that annoy them – Vitamin D and interpretation of tests. We find there is no value to using Vitamin D to prevent acute respiratory infections and that as health care providers we overestimate the probability of diagnoses before and after testing.

Episode 483: Aducanumab for Alzheimer’s – forget about it?

In episode 483, James and Mike invite Tina to the podcast to talk about the aducanumab (Aduhelm) FDA approval story. We look at all the latest evidence, we talk about how people analyzed the data, whether or not the findings were clinically important, the side effects and finally the cost. And no matter how we looked at it we were still puzzled it got FDA approval. What do you think?
