Continuous variables with normal distribution were expressed as the mean ± standard deviation (SD), non-normal variables were expressed as the median (interquartile range (IQR)), and categorical data were expressed as number and percentage. The independent sample Student's t-test was used to compare the means of two continuous normally distributed variables. The means of two non-normally distributed variables were compared with the Mann–Whitney U test. The frequencies of categorical variables were compared by the χ2 test.
