- aThe time before RFA was not included for comparison
- bAccording to the society of interventional radiology classification
- ***Fisher’s exact test
- RFA radio frequency ablation, RLV remaining liver volume, TBIL total bilirubin
- Ablation size was evaluated by ultrasonography after RFA
- RLV=SLV-ablation volume, ablation volume was calculated based on the formula of sphere volume
