Results comparison for RFA vs. HR meta-analyses [31, 32] with current study for a categorical and b continuous outcomes. *Feng, 2015 reported recurrence-free survival, where DFS was reported by the current study. †The ORs for complications have been inverted so that the favored treatment labels agree with those for the survival outcomes. ORs were calculated for the current study (MWA vs. HR) for comparability with outcome measures from Feng, 2015. Abbreviations: DFS, disease-free survival; HR, hepatic resection; MWA, microwave ablation; OR, odds ratio; OS, overall survival; RFA, radiofrequency ablation; RFS; recurrence-free survival; WMD, weighted mean difference
