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

Table 3 Multivariate analysis to identify risk factors that contributed to a worsening Child-Pugh scores following radiofrequency ablation (n = 123)

Variable	HR	95%CI	P-value
CP class (B vs A)	5.07	2.13-12.1	0.000
Platelet count (104/μL) (< 10 vs≥ 10)	3.83	1.36-10.8	0.011
AST (IU/L) (≥ 40 vs < 40)	7.01	1.30-37.9	0.024
ALT (IU/L) (≥ 35 vs < 35)	1.21	0.35-4.19	0.761

A worsening Child-Pugh (CP) scores was defined as a 2 point increase. AST: Aspartate aminotransferase; ALT: Alanine aminotransferase.
