- *P < 0.05, **P < 0.01, ***P < 0.001. Student’s t-test versus males
- a Subjects in the Tromsø study with valid food frequency questionnaires, serum 25(OH) D measurement, not been on a sunny vacation last 2 months, and not taking solarium regularly
- b As in the main cohort but with valid serum PTH measurement and with serum calcium < 2.51 mmol/L
- cIncluding supplements
- The data are mean (95% CI). The P values are not adjusted for multiple testing
