Comparison of the EHRA symptom scores at baseline and follow-up in the CBA and RFA groups. This 100% stacked column chart depicts the differences in the EHRA symptom score distribution at baseline and follow-up in the CBA and RFA groups. Results are displayed as the percentage of patients. In both groups, a significant improvement was observed with P < 0.001. In the RFA group, patients more frequently demonstrated an EHRA score of 3 or 4 at baseline as compared to the CBA group (80.1% vs. 47%, P < 0.001), and an EHRA score of 2 was more often documented in the CBA group. Improvement in the EHRA score of at least one class was observed in 76.3% and 84.9% of the patients in the CBA and RFA groups, respectively (P < 0.0001). More patients in the CBA group demonstrated an EHRA score of 1 (no symptoms) at follow-up (75.5% vs. 70.5%, P < 0.01). CBA, cryoballoon ablation; EHRA, European Heart Rhythm Association; RFA, radiofrequency ablation.
