> Vitamin D also stabilizes plaques in arteries by reducing macrophage activation.

Well, that is strange though. Because if you have such an effect, should you not include this? If macrophages are less active, perhaps infection rates go up, which can contribute to death. Perhaps not to the amount of the 52% gains mentioned here, but the website does not mention this at all whatsoever; the word "macrophages" occurs only twice on total.
