Data are shown using count (percentage) or mean (standard deviation). P values were calculated with chi-squared tests and Student's t tests for categorical and continuous variables, respectively
* These variables are also presented as medians (interquartile ranges), and their p values were calculated with the Wilcoxon rank sum test
