Data with normal distribution are presented as mean ± SD and data with nonnormal distribution are presented as median, interquartile range.
P values were calculated by paired T test for normal distribution variables and Wilcoxon signed-rank test for nonparametric tests. We used linear models and Friedman's test to analyze repeated measurement at baseline and 4 and 12 weeks when needed.
