2. Figure 1
Comparison of the local tumor progression rate for main tumor across the conventional PEI, higher-dose PEI, and RF ablation groups. The rate was significantly lower in the RF group than in the other 2 groups (RF vs conventional PEI, P = .012; RF vs higher-dose PEI, P = .037). The difference between RF and conventional or higher-dose PEI becomes clear by looking at the data on a year-by-year basis. closed square, conventional PEI group; closed triangle, higher-dose PEI group; closed circle, RF group.

3. Figure 2
Comparison of the overall survival rate across the conventional PEI, higher-dose PEI, and RF ablation groups. The rate was significantly higher in the RF group than in the other 2 groups (RF vs conventional PEI, P = .014; RF vs higher-dose PEI, P = .023). The difference between RF and conventional or higher-dose PEI becomes clear by looking at the data on a year-by-year basis. closed square, conventional PEI group; closed triangle, higher-dose PEI group; closed circle, RF group.

4. Figure 3
Comparison of the cancer-free survival rate across the conventional PEI, higher-dose PEI, and RF ablation groups. The rate was significantly higher in the RF group than in the other 2 groups (RF vs conventional PEI, P = .019; RF vs higher-dose PEI, P = .024). The difference between RF and conventional or higher-dose PEI becomes clear by looking at the data on a year-by-year basis. closed square, conventional PEI group; closed triangle, higher-dose PEI group; closed circle, RF group.
