Responsiveness results of unidimensional tools. Empty cells indicate data not available or not assessed. ∗P-value is statistically significant at <0.0001. ^†Knee surgery. ^‡Laparotomy. ^¶VAS score. ^§CPI score. ^||Time 2 vs time 1. ^#Time 3 vs time 1. ^††Time 4 vs time 1. ^‡‡Time 5 vs time. ^¶¶Results for younger patient split of the sample at the median age of 62 yr. CCPS, colour circle pain scale; CI, confidence interval; CPI, categorical verbal pain rating scale; FPS, face pain scale; G, group; MPQ, McGill pain questionnaire; PPI, present pain intensity; PROM/s, patient-reported outcome measures; SRM, standardized response mean; VAS, visual analogue scale; VAS-R, visual analogue scale at rest; VAS-M, visual analogue scale at movement; VDS, verbal descriptor scale. Effect size, calculated by taking a mean change of variable and dividing it by standard deviation of that variable.
