Continuous variables were expressed as median [Interquartile range] and compared between groups will be performed using the Kruskal-Wallis H rank-sum test. Categorical variables were expressed as numbers (percentages), and comparisons between groups were performed using the chi-square test or Fisher’s exact test if a cell count was less than 5. *P < 0.05
