  1. Model 1: no covariates were adjusted. Model 2: age, gender, race were adjusted. Model 3: all the covariates in Table 1 were adjusted
  2. *In the subgroup analysis stratified by each covariate, the model is not adjusted for the stratification variable itself
  3. '/' represented restricted sample size
