Subgroup analyses in patients with the Child-Pugh grade B (n = 21). There were six patients with the Child-Pugh grade B in the obesity group and 15 in the control group. In terms of OS (a), there was no significant difference between the two groups (P = 0.112). However, RFS rates in the obesity group were significantly higher than those in the control group (b) (P = 0.018).
