Fig. 3From: The effect of anatomical variables and use of the Lifts system on hearing outcomes after implantation of an active transcutaneous bone conduction device in bilateral congenital conductive hearing lossROC curves of AP dimension. The AP had high accuracy for (AUC = 0.947) dural or sigmoid sinus compression (AUC = 0.913). AUC = area under the receiver operating characteristic curve; ROC = receiver operating characteristic; AP = the mean antero-posterior mastoid bone thickness from the external auditory canalBack to article page
