Table 3 ROC and MCIC estimates according to patient perceived important change in main complaint

From: Measurement properties of the musculoskeletal health questionnaire (MSK-HQ): a between country comparison

Cut points n (%) ROCAUC (95% CI) MCICROC Sensitivity/ specificity % MCICpercent

  1. a) Large improvement (much better, better versus a little better, unchanged, little worse)
  2. b) Small improvements (much better, better, little better versus unchanged)
  3. MCICROC: Estimated as the optimal cut-off point of the ROC curve using absolute change scores
  4. MCICpercent: Estimated as the optimal cut-off point of the ROC curve using relative change scores
  5. Abbreviations: ROC receiver operating characteristic, AUC area under the curve, CI confidence interval
