Figure 2 12-month survival rate according to cycles of anti-PD-1. (A) The 12-month survival rate (y-axis) according to the median cycles of anti-PD-1 in subpopulations (x-axis) through subpopulation treatment effect pattern plot analysis (STEFF). (B) Overall survival of the monotherapy and combination groups.

Notes: The combination group only included 59 patients with 4 cycles anti-PD-1 plus lenvatinib, while the other 11 patients with 3 cycles anti-PD-1 plus lenvatinib were put into the monotherapy group.

Figure 3 Overall survival according to the composite risk scores. (A) 12-month survival rate (y-axis) by median composite risk scores in subpopulations (x-axis). (B) Overall survival by the quartile of the composite risk scores. (C) 12-month survival rate (y-axis) according to the median composite risk scores in subpopulations (x-axis) through subpopulation treatment effect pattern plot analysis (STEFF). (D) The difference in 12-month survival rate (y-axis) between the combination and monotherapy groups according to the median composite risk scores in subpopulations (x-axis). The light grey vertical dashed lines indicate the median composite risk score of 0.74.
