  1. Data are presented as mean ± standard deviation (SD) or median (inter-quartile range) for continuous variables, and as frequency or percentage for categorical variables. For baseline characteristics analysis, the statistical differences among three groups were tested with t-test or one-way ANOV A for continuous variables and chi-square or fisher test for categorical variables
