Analysis for women:
Gehan’s modified Wilcoxon test (W):
W VVI/R vs. DDD/R = –7.43 p < 0.001
W VVI/R vs. AAI/R = –5.66 p < 0.001
W VVI/R vs. VDD/R = –2.99 p < 0.01
W DDD/R vs. AAI/R = –0.03 p > 0.05
W DDD/R vs. VDD/R = –0.26 p > 0.05
W AAI/R vs. VDD/R = 0.31 p > 0.05
Analysis for men:
Gehan’s modified Wilcoxon test (W):
W VVI/R vs. DDD/R = –5.10 p < 0.001
W VVI/R vs. AAI/R = –4.46 p < 0.001
W VVI/R vs. VDD/R = –2.77 p < 0.01
W DDD/R vs. AAI/R = –1.81 p > 0.05
W DDD/R vs. VDD/R = –0.47 p > 0.05
W AAI/R vs. VDD/R = 0.97 p > 0.05
