Comment Comment by rdmcfee Sure, the correlation is statistically significant. Without a control to infer causality the results become much less interesting.To infer causality in an epidemiological study such as this you need very large cohorts with very specific results.Even with huge cohorts you still have relatively indefensible results. The 7 country study is a good example: https://en.wikipedia.org/wiki/Seven_Countries_Study parent rdmcfee 10 years ago
