Figure 2

The comparison of the ablated nodular VRRs between the RFA and MWA groups at each follow-up period. At 3-month follow-up, the mean VRR between the two groups showed no significant differences (p = 0.143), but after that, statistical significance was observed and a higher VRR was shown in the RFA group than in the MWA group. The mean ± standard deviation is illustrated. (VRR: volume reduction ratio; RFA: radiofrequency ablation; MWA: microwave ablation; RF_VRR: the mean nodular VRR in the RFA group; MW_VRR: the mean nodular VRR in the MWA group; mo: months; FU: follow-up).
