Note. HLG = healthy liver group; CLG = cirrhotic liver group; mm = millimeters; LAD = long axis diameter; SAD = short axis diameter; mSAD = mean SAD-1 and SAD-2; mSPH = mean sphericity. Ablation zone parameters for the CLG and HLG are presented as mean ± standard deviation [min-max]. Main effects and interactions were tested in a 2 × 2 mixed model ANOVA (group by time), controlling for gender. Significant main effects and interactions (p < 0.05) are presented in bold.
