ROC curve analysis of the PLR, APPLE score and APPLE score plus PLR to predict recurrence in AF patients after catheter ablation. The area under the curve (AUC) of the APPLE score, PLR and addition of the PLR to the APPLE score for predicting recurrence was 0.645 (95% CI, 0.601 to 0.690; P < 0.001), 0.596 (95% CI, 0.557 to 0.634; P < 0.001) and 0.675 (95% CI, 0.629 to 0.722), respectively; APPLE vs APPLE + PLR, P=0.019; The circle on the curve indicates the point corresponding to the optimal cut-off value.

Abbreviations: AF, atrial fibrillation; ROC, receiver operating characteristic; PLR, platelet to lymphocyte ratio.
