Serum 25-Hydroxyvitamin D and Risks of Colon and Rectal Cancer in Finnish Men
TL;DR: The results provide no evidence to support an inverse association between vitamin D status and colon or rectal cancer risk; instead, they suggest a positive association for colon cancer.

TL;DR: In this article, the authors used stepwise linear regression and polytomous logistic regression to identify persons at risk for low vitamin D status for both clinical and research purposes, and found significant positive and significant inverse correlates of 25(OH)D included male sex, summer blood draw, vigorous physical activity, vitamin D intake, fish intake, multivitamin use, and calcium supplement use.
