Randomization and allocation factor
PAF
The patients will be registered and randomly assigned to either the CB or RF ablation group in a 1:1 ratio using a UMIN INDICE cloud system. The treatment allocation will be based on a covariate‐adaptive randomization (minimization) scheme including the age (<70 vs. ≥70 years), AF type (PAF vs. PeAF), and LAD (<50 vs. ≥50 mm), as covariates.
