Episode 109: More, questions, questions and more questions
In episode 109, Mike and James continue on with listener questions and start off trying to reduce the risk of using risk assessment tools and risk reduction information. They then delve into questions about tapering steroids, antidepressants, side effects from thiazides and sitagliptin and the amazing clarity of their answers is only outdone by the vagueness of their conclusions.
