Calculated MCID values for each method
| MCID method | MCID (gain in MO) (T1) (mm) | MCID (gain in MO) (T2) (mm) | % of patients who obtained a change greater than or equal to that of each MCID method (T1) | % of patients who obtained a change greater than or equal to that of each MCID method (T2) |
|---|---|---|---|---|
| Mean change method | 14.89 | 11.75 | 51.4 (18/35) | 51.4 (18/35) |
| Change difference method | NC | 9.75 | NC | 57.1 (20/35) |
| ROC curve | 11.5 (sensitivity 81.8% and specificity 100%) | 10.5 (sensitivity 73.9% and specificity 83.3%) | 77.1 (27/35) | 54.3 (19/35) |
| AUC | 0.902 | 0.873 |
(MCID: minimal clinically important difference, MO: mouth opening, ROC: receiver operator characteristic, AUC: area under the curve, NC: cannot be calculated due to data discrepancy)
