The 48th Annual Meeting of the Society for Epidemiologic Research took place in Denver, Colorado 16-19 June 2015. For me, the highlight of the Meeting was the 2015 Keynote Cassel Lecture delivered by Dr Judea Pearl: The Scientific Approach to Causal Inference.

Well, it's October, and the World Series is under way. Good time to talk baseball I'd say. So here's a blast from my own past on the subject: Simpson's Paradox and Major Leagues Baseball's Hall of Fame.1
One of the most important aspects of good research is proper study design; no type or amount of statistical analysis can make up for a poorly designed study. In longitudinal research one of the most important aspects of study design is making sure that the temporal sequence of events is understood and recorded correctly. Errors in this arena can lead to misclassification of exposure time and differential follow-up between comparison groups. It is therefore crucial to understand time at risk in studies and correctly and fairly apply rules of follow-up to study subjects.
