Figure 2.

Kaplan–Meier analysis was applied for the assessment of survival.

Notes: Student’s t-test was performed to identify the predictors for local efficacy. Log-rank analysis was performed to identify the predictors for survival. (A) Local efficacy was significantly correlated with MWA-related PFS (P=0.003). (B) Time interval between best overall response and initial MWA was significantly correlated with PFS (P=0.011). Local efficacy was a predictor of both MWA-related OS (P=0.000) (C) and OS (P=0.001) (D).

Abbreviations: MWA, microwave ablation; PFS, progression-free survival; OS, overall survival; d, days.
