Ablation time to roll-off, maximum output, and coagulation diameter

	Group with RFA alone	Group with RFA following LP-TAE	P value
Ablation time to roll-off (s)	445.1 ± 35.9	320.6 ± 30.9	P < 0.05
Maximum output (W)	87.0 ± 4.83	69.0 ± 7.38	P < 0.05
Coagulation diameter (mm)	33.2 ± 2.28	41.7 ± 3.85	P < 0.05

Significant reductions in roll-off time and output and significantly greater coagulation diameter were obtained with RFA following LP-TAE compared with RFA alone. LP-TAE: Transcatheter arterial embolization with iodized oil (Lipiodol); RFA: radiofrequency ablation.
