^aOR, odds ratio; CI, confidence interval.

^bp-value obtains from Wald test. In both women and men, the second model adjusted for age, systolic blood pressure, diastolic blood pressure, education years, and osteoarthritis. The third model adjusted for those in the second model and height and weight. The p-value of lower than 0.05 were presented in boldface.
