  1. Continuous variables were expressed as mean ± standard deviation (SD) for normally distributed variables, median (IQR) for non-normally distributed continuous variables, and numbers (%) for categorical variables. The T test or one-way ANOVA was used to compare continuous variables, while Pearson’s χ2 test was used to compare categorical variables when examining baseline characteristics
