As was hinted to earlier, when it comes to strokes it depends on whether you're at risk for ischemic or hemorrhagic stroke. With the latter, an aspirin regimen will shorten your journey to the afterlife.
The bottom line in my view is what I was referring to previously, which is that treatment needs to be decided on an individual basis, by a thinking and reasoned physician, and NOT on the basis of an algorithm defined by a flawed statistical study. There is no such thing as a perfect algorithm when you are dealing with biological diversity.
