Wrong, I do not have a hypothesis (or any sort of preconceived notion). I am just curious to see what the data shows about risk stratification across age groups with and without common risk factors. Do you have any references to recent peer reviewed studies on that topic?

I'm not sure why you're trying to derail the discussion by bringing up data dredging. That would only potentially be relevant as a possible criticism of the methodology in a particular study. So what's your point?
