The way I understand how the rules work for the medication data sheets is that EVERY adverse health condition that arises in any patient during the trials gets listed - but the vast majority of them are red herrings because they could be caused by lots of things, not necessarily the medicine and unless a condition gets report by a bunch of patients, there is no further analysis of cause & effect. I tend to pay more attention to the list of common side effects and ignore the list of rare side effects because every data sheet's rare effects are scary.
