3.3 Prediction for the risk of AF recurrence based on DC
post-ablation
There are 5 studies reporting the ratio predicting for AF recurrence
based on post-ablation DC. The pooled OR calculated with the
random-effect model was 2.17 (Figure 4; 95%CI, 1.44 to 3.25; P< .01), suggesting that the high DC post-ablation was a risk
factor for AF recurrence in patients treated with CA. One of these
studies reported the HR estimated with the Cox regression analysis to
predict AF recurrence, which might account for the significant
heterogeneity (I 2 = 76.1%, P< .01). Similar results were retrieved in the sensitivity
analysis (Supplement 1D). The funnel plot regarding ORs based on DC was
presented in Supplement 2D.
