Figure 4. ROC analyses for the prediction of lesion formation without a gap
ROC curves incorporating various impedance parameters revealed that LI drop had the largest area under the curve for prediction of lesion formation without a gap. An LI drop of 15 ohm demonstrated the best predictive value, with a sensitivity of 0.71, specificity of 0.81, and predictive accuracy of 0.75.
ROC indicates receiver-operator curve; Se, sensitivity; Sp, specificity; Ac, predictive accuracy
