  1. * Intergroup differences for the changes from baseline to week 16 were determined by the Kruskal-Wallis test followed by Mann–Whitney U-test: A P < 0.05 vs physical exercise. Within group changes were determined by Wilcoxon rank-sum test: a P < 0.05 (acupuncture group); b P < 0.01 (acupuncture group); c P < 0.001 (acupuncture group); d P < 0.05 (exercise group); e P < 0.001 (exercise group); f P < 0.05 (control group); g P < 0.001 (control group).
