- Continuous normally distributed variables were expressed as the mean ± standard deviation (SD); Continuous non-normally distributed variables were expressed as the median (interquartile range); categorical variables are expressed as the number (percentage). Independent sample t-test was used to compare the differences between the means of two continuous normally distributed variables and Mann-Whitney U test was used to compare the differences between the means of two continuous non-normal distribution variables. Chi-square test was used to compare the differences between the categorical variables
