HR, hazard ratio; CI, confidence interval; AIT, ablation index tumor; LTP, local tumor progression; NA, not applicable.
*Only variables with
†Comparisons of 4 or 5 AITs with multiple variables.
‡LTP is an event that terminates progression-free survival, and because it consequently causes high HR and bias, this parameter was not included in the multivariate analysis.
