  1. Agreement between blinded observers and ‘gold standard’, assessed by weighted kappa coefficient (95% CI), for each scale item, at all time points (preoperative, postoperative before and after analgesia, and 24 hours after the end of surgery) and for T2 (postoperative before analgesia) independently.
  2. Interpretation: 0.81 – 1.0 very good; 0.61 – 0.80 good; 0.41 – 0.6 moderate; 0.21 – 0.4 fair; < 0.2 poor.
