AUC value, sensitivity, and specificity of ROC curve for RRI.
| Scale | AUC | 95% CI | p value | Cut-off point | Sensitivity | 1-Specificity | Yuden's J | K-index | DIFF | |
|---|---|---|---|---|---|---|---|---|---|---|
| Lower bound | Upper bound | |||||||||
| RRI | 0.664 | 0.541 | 0.786 | 0.04 | 102 | 1 | 0.683 | 0. 492 | 0.279 | 0.2 |
Note. p ≤ 0.05; AUC = area under curve; CI = confidence interval; D value or K-index = Sqrt [(1 − sensitivity)2 + (1 − specificity)2; DIFF = abs (sensitivity − specificity) [42].
