Model 1: no covariates were adjusted. Model 2: age and race were adjusted. Model 3: age, race, body mass index, education level, income to poverty ratio, moderate activities, age since menopause, blood urea nitrogen, serum uric acid, total protein, serum phosphorus, and serum calcium were adjusted. , , and .
