The Predictive Value of Growth Differentiation Factor-15 in Recurrence of Atrial Fibrillation after Catheter Ablation

Figure 1

ROC curve analysis to determine the predictive value of GDF-15 for AF recurrence. AF: atrial fibrillation; AUC: area under the curve; CI: confidence interval; ROC: receiver operating characteristic; GDF-15: growth differentiation factor-15.
