...to point out that a 15% change cannot be evaluated for true clinical (or statistical) significance without knowing the base rate.
My bad.

I still find it fascinating, though, how this kind of information is spun -- I can easily imagine the same data being presented as "Vitamin D supplements drop cancer risk up to 15%!!!" instead of "Vitamin D supplements don't reduce cancer risk any more than 15%." No wonder people get so confused about what the hell research actually means...

I take vitamin D at my MD's recommendation, after blood-work showed a deficiency several years ago. I'm looking forward to reading the actual study when it's published.
