^aHR, hazard ration. CI, confidence interval, WC stable trajectory was reference group
Model 1 was unadjusted model without any covariates
Model 2 adjusted age, gender, enrollment year, education and income level, smoking and drinking status, physical activity levels, initial BMI and WC, initial SBP/DBP, dietary energy intake and chronic disease
Model 3 adjusted propensity score of aforementioned covariates as a linear and only covariate
