Device implantation duration as risk factor for retained leads. Univariate and multivariate logistic regression analyses identified the duration between implantable cardioverter-defibrillator implantation and heart transplantation as an independent predictor for retained lead fragments (P < .05), with a cutoff of 38 months (sensitivity 0.778 and specificity 0.608). AUC, area under the receiver operating characteristic curve.
