Brink and colleagues in Sweden found no link between vitamin D and the development of rheumatoid arthritis (RA); however, they did observe that increased levels of vitamin D–binding protein in a small portion of women raise the risk of RA.1 Scroll through the slides for the details of the study and the take-home points for physicians.
