P1: The coefficient of rank correlation between the SF-36 subscale scores and the NRS scores
P2: The coefficient of rank correlation between the SF-36 subscale scores and the SCAR scale scores
Correlation coefficients: 0–0.20 = “week”; 0.21–0.40 = “fair”; 0.41–0.60 = “moderate”; 0.61–0.80 = “strong”; 0.81–1.00 = “strongly correlation”
