Numerical variables were presented as median (interquartile range) or mean ± standard deviation. Categorical variables were expressed as counts (percentage). Numerical variables were analyzed by Mann-Whitney U-test or unpaired Student t test. Categorical variables were analyzed by chi-square test or Fisher exact test.
