Ditto all that, plus the mortality rate in the (very small) comparison group was 44%, which is very high even for the elderly. The mortality rate for the vit D group was not really all that great. On the flip side, given that they comparison group were receiving vit D3 occasionally, just not lately, it is possible that this underestimates the impact of vit D3 on a group that had long-term insufficient vit D3. Nothing here to say that vit D isn't good for you, especially if you have a deficiency (such as from insufficient time in the sun), but not a stunning piece of info either.
