The normality of continuous variables was examined by Shapiro-Wilk test. The continuous variables that confirmed to normal distribution were expressed as mean ± standard deviation (SD), and compared by independent sample t-test. The continuous variables with skewed distribution were expressed as median (P25, P75), and compared by the Mann-Whitney U test
