CI, confidence interval; AIT, ablation index tumor.
*Indicates the effect of 4 or 5 AITs among 3 variables.
†Because of the patient-based nature of the study, all patients with an ablated lesion greater than 30 mm in diameter were included in this group.
‡Median survival rates are presented on a monthly basis. Values in parentheses are the standard error values.
