  1. Continuous variables that followed a normal distribution were evaluated using weighted t-tests, whereas those that were not normally distributed were analyzed through the weighted Wilcoxon rank-sum test
  2. Percentages (weighted N, %) for categorical variables: the P value was calculated by the weighted chi-square test
