ZBMI: Body mass index (BMI) z score

B: un-standardized regression coefficient

SE: standard error

p: p-value testing the significance of the regression coefficient

R²: variance explained by the regression model

p (△F): p-value testing the significance of F change from the preceding model (^#model 1 includes only the intercept term)

ref: reference group of the categorical variable analyzed by creating dummy variables

* Cardiometabolic risk score β includes all components of risk score α except waist circumference
