  1. a: multivariate logistic regression model without propensity score weighting, the HDL was cut by quantile
  2. b: multivariate logistic regression model without propensity score weighting, the HDL was cut by 1.03 mmol/l.
  3. c: multivariate logistic regression model after propensity score weighting, the HDL was cut by 1.03 mmol/l.
