The between-group value was calculated by Mann–Whitney U test. The within-group value was calculated by Wilcoxon signed rank test. The value was statistically significant under the adjusted significant level as 0.025 based on Bonferroni correction. The test group included 40 males and 24 females, and the control group included 41 males and 11 females.
