Vitamin D and mortality: Individual participant data meta-analysis of standardized 25-hydroxyvitamin D in 26916 individuals from a European consortium
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-02-16)

We therefore performed an IPD meta-analysis on the association between standardized serum 25(OH)D and mortality.<br>Methods:<br>In a European ...
