  1. Models adjusted for age, sex, income group, BMI, smoking, alcohol consumption, and nutritional intake (total calories, protein, fat, carbohydrate intake, calcium, phosphorous, and potassium intake)
  2. Crude and adjusted odds ratios (95% confidence interval) were calculated by using multiple logistic regression analyses
