Calcium plus Vitamin D Supplementation and the Risk of Colorectal Cancer
Randomized trial
From conclusions:
“Daily supplementation of calcium with vitamin D for seven years had no effect on the incidence of colorectal cancer among postmenopausal women.”
Misleading conclusion. Their 400 IU dose of Vit D was pathetically low and therefore totally ineffective. However if you look at table 2, you’ll see that their data show that serum vit. D level was strongly inversely linked to colorectal cancer.

Lastly, liking/disliking is for measuring the quality of the Arbital page itself. To express your belief that the paper is not effective, you should cast a probability vote, which I just added to this page.
Thanks, duly noted.
