Interesting... Meta studies are suspect, as the results are based on extrapolated numbers from inconsistent or non-standardized structured older studies. Generalities are often used to construct general studies... yeah.
Something to consider... the negative aspirin recommendations, leave an open door for newer blood thinners such as Xarelto or Eliquis... which, instead of a dollar store bottle of 30 baby aspirin @$1... cost about $525.00 for the same 30day period.
Not to insinuate anything nefarious, but Physicians are often paid substantial
$$$. to "report" results of their patients who take those recommended drugs, instead of low dose aspirin.
A second part of the questions that arise from newer studies, is whether or not the published results give general conclusions, or more specific numbers that the reader can use to determine ones' own treatment. One of the major conclusions that I have taken from looking at the more in-depth studies is that the difference between the death-risk factors for some conditions... changes from 2.9% to 1.8%. with the use of the more expensive medications.
No.. you are right.. I'm not a doctor, just a matter of making a decision of whether the risk difference is worth $12 or $6000 per year.
I mean that's just one set of odds... does not include being killed in a car crash, or being hit by a comet.
