So what are we to make of this quandary & contradictory evidence. First, let's recall that science is never that clear cut & transparent. Second, in the big scheme of things, 5-6 year studies of 800-1900 participants is neither long nor large enough. Third, observational studies such as these are useful for developing hypotheses but not for proving cause & effect. But with all that said, I can't think of a single reason (aside from anaphylactic allergy) not to lower one's blood pressure and pray for secondary benefit, even as we wait for more definitive proof.
