Unadjusted model adjust for: None.

Minimally adjusted model adjust for: age, gender, race.

Fully adjusted model adjust for: age, gender, race, BMI, income-poverty ratio, education level, alkaline phosphatase, cholesterol, calcium, phosphorus, globulin, and total protein.

Gender is not adjusted in the subgroup analysis stratified by gender, and age is not adjusted in the subgroup analysis stratified by age. *P < 0.05, **P < 0.01, ***P < 0.001.
