Table 6 ORs (95 % CIs) for CAC by quartiles of serum vitamin D levels in women (n = 5510)

From: High levels of serum vitamin D are associated with a decreased risk of metabolic diseases in both men and women, but an increased risk for coronary artery calcification in Korean men

  Quartiles of serum vitamin D levels p for trend
Q1 (<9.8 mg/dL) Q2 (9.8–13.0 mg/dL) Q3 (13.0–17.6 mg/dL) Q4 (≥17.6 mg/dL)
n = 1380 n = 1378 n = 1378 n = 1374
