True, finding the reasons for a correletion is absolutely necessary if you have only one study. However, in this case they are numerous, and they all show the same trend. That Pucher still hesitates to speak of a regular causation has to do with the fact that finding the causes is a very complex matter which would take a very thorough (and costly) investigation. What we DO have are several papers telling us what most cyclists (potential as well as actual) want, from both America and Europe, and as these seem to correlelate with the other correlation, so to speak, the case IS quite strong.
So having three studies that find that most people who died, ate their vegetables within the prior week; gives us a very strong case that eating vegetables will kill you.
