a Range of absolute minimal clinically important differences in acute pain assessed by the mean change approach* (29 studies, 6517 patients). *MCID assessed as the mean change in pain score among patients with minimal improvement of pain, MCID = Minimal Clinically Important Difference (mm reduction on a 100 mm scale), Studies where standard error (or data for obtaining this) was unavailable are presented as point estimates without 95% CI (NA = not applicable). b Range of relative minimal clinically important differences in acute pain assessed by the mean change approach* (14 studies, 1617 patients). *MCID assessed as the mean change in pain score among patients with minimal improvement of pain, MCID = Minimal Clinically Important Difference (% reduction from baseline), Studies where standard error (or data for obtaining this) was unavailable are presented as point estimates without 95% CI (NA = not applicable)
