borderline significanceP = 0.07
In the subgroup of patients with persistent AF, there was borderline significance in secondary effectiveness with the use of posterior wall ablation (68% vs. 51%, P = 0.07).

While our study showed a near-significant effectiveness of posterior wall ablation in PersAF patients, this finding is at best hypothesis generating: this near-significant finding was achieved in patients undergoing repeat (not initial) ablation, with difference in subgroups in terms of baseline characteristics, lesion set during initial ablation, and ablation energy used during repeat ablation.
