Table 3. AUC and pairwise comparison of ROC curves in uroflowmetry parameters.
Variable | AUC | Comparison AUC of ROC curve (p-value) | |||
---|---|---|---|---|---|
vs. Qmax | vs. Qave | vs. DeltaQ | vs. PVR | ||
Qmax | 0.763 | - | <0.0001* | 0.0168* | 0.3846 |
Qave | 0.574 | <0.0001* | - | <0.0001* | <0.0001* |
DeltaQ | 0.806 | 0.0168* | <0.0001* | - | 0.8188 |
PVR | 0.796 | 0.3846 | <0.0001* | 0.8188 | - |
AUC, area under the curve; ROC, receiver operating characteristic; Qmax, maximal flow rate; Qave, average flow rate; DeltaQ, delta Q (Qmax minus Qave); PVR, postvoid residual urine.
