FIGURE 2 Comparison of factors during ablation among the three groups. A, The average NT was significantly lower in the CST success group than in the CST failure group. B, The percentage of complete occlusion of the superior PV with CB was significantly higher in the CST success group than in the other groups*. 95% confidence intervals are shown in (A), whereas 98.3% confidence intervals are shown in (B). *: p<0.0167 was considered significant, with adjustment by Bonferroni correction. CB, cryoballoon; CST, crosstalk; NT, nadir balloon temperature; PV, pulmonary vein
