NBIW: n = 8, Control: n = 6.
Values are shown as mean (SD).
Within-group comparison: Significant differences were found compared with before the intervention (* p < 0.05: Wilcoxon signed rank test).
Between-group comparison: Significant differences between group (# p < 0.05, ## p < 0.01: Wilcoxon rank sum test).
