  1. Data were presented as mean (SD) or n (%)
  2. Continuous variables were represented as mean ± SD; categorical variables were expressed as numbers (percentages); the Kruskal–Wallis rank test was used for continuous variables and the chi-square test for categorical variables, and when the expected value was < 10, the Fisher’s exact test was used
