Each outcome was binary based on MetS cutoff points; for blood pressure, either or both systolic (≥130 mmHg) and diastolic (≥ 85 mmHg) blood pressure or blood pressure lowering medication use were used as binary (yes/no).
The values are relative risk and 95% confidence intervals from models adjusted for total calcium intake, age, gender, race, region, education, income, smoking, alcohol intake, regular aspirin use, total calorie intake, physical activity, and baseline values of the components of MetS
Abbreviation: CI, confidence interval; HDL, high-density lipoprotein cholesterol; RR, relative risk; WC, waist circumference
