Efficacy and safety of computed tomography-guided microwave ablation with fine needle-assisted puncture positioning technique for hepatocellular carcinoma

Figure 4 Comparison of cumulative incidence of local tumor progression, recurrence-free survival, and overall survival following post-computed tomography-guided microwave ablation between fine needle-assisted puncture positioning and conventional puncture groups. A: Local tumor progression (P = 0.038 based on log-rank statistics); B: Recurrence-free survival (P = 0.008 based on log-rank statistics); C: Overall survival (P = 0.229 based on log-rank statistics). CP: Conventional puncture; FNP: Fine needle-assisted puncture positioning; LTP: Local tumor progression; OS: Overall survival; RFS: Recurrence-free survival.
