Major finding: The risk of developing RA in individuals aged 18-33.9 years was not significantly different among those in the highest vs. lowest vitamin D quintile (adjusted hazard ratio 1.21; 95% CI 0.90-1.63).
Study details: This was a registry-based case-cohort study involving 805 patients with RA with onset in early adulthood and 2,416 individuals from a random subcohort.
