  1. The results of sensitivity analyses using the alternative criteria for type classification are shown (original criteria: type S, < 0.75; type C, ≥ 1.55; type SC, ≥ 0.75 and < 1.55). Values are mean ± standard deviation. Bold indicates statistically significant. VAS visual analog scale, PCS physical component summary
