Logistic regression models:

Model 1: no covariates were adjusted

Model 2 was adjusted for demographic factors, including gender, age, and race

Model 3 was adjusted for gender, age, race, education, physical activity, smoking behavior, alcohol consumption, BMI, WC, HbA1c, albumin, blood urea nitrogen, total calcium, creatinine, phosphorus, triglycerides, and uric acid
