Risk factors for deterioration of long-term liver function after radiofrequency ablation therapy

Figure 1 Cumulative rate of worsening Child-Pugh scores (defined as a 2-point increase) for all patients. The 1-, 2-, 3-, 5- and 7-year cumulative rates for worsening CP scores calculated according to the Kaplan-Meier method were 2.4%, 6.9%, 10.0%, 19.3% and 33.2%, respectively. CP: Child-Pugh.

Figure 2 Comparison of cumulative rate of worsening Child-Pugh scores (defined as a 2-point increase) according to the Kaplan-Meier method. P-values were calculated using a log-rank test. Analysis according to: A: CP class: A (n = 102) and B (n = 21); B: Platelet count: < 10 × 10⁴/μL (n = 54) and ≥ 10 × 10⁴/μL (n = 69); C: AST levels: < 40 IU/L (n = 39) and ≥ 40 IU/L (n = 84). CP: Child-Pugh; AST: Aspartate aminotransferase.
