Model 1: no covariates were adjusted.
Model 2: age and race were adjusted.
Model 3: age, race and body mass index were adjusted.
Model 4: age, race, educational level, menstrual status, history of hypertension, history of diabetes, history of cancer or malignancy, body mass index, moderate recreational activities, total protein, blood urea nitrogen, serum uric acid, and serum calcium were adjusted.
