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
