Legend: Data are presented as n (x%) for dichotomous variables, mean (±SD) for continuous demographic variables with normal distribution and median [interquartile range] with non-normal distribution. * The chi-square test or Fisher’s exact test with, if necessary, the exact calculation of Fisher, was used for the ordinal or nominal data analysis. We used the Student’s t-test to compare age and BMI.
