Forest plots of the favored effect of TACE for 6-month OS. The plot was based on the liver function, Child–Pugh A or B. (A) Subgroup analysis in HCC with PVTT. (B) Subgroup analysis in HCC with MPV invasion only. Each line represents an individual study result with the width of the horizontal line indicating 95% CI, the position of the box representing the point estimate, and the size of the box being proportional to the weight of the study. (KM Kim-1, 3: subgroup MPV invasion or segmental PVTT in HCC with Child–Pugh A; KM Kim-2, 4: subgroup MPV invasion or segmental PVTT in HCC with Child–Pugh B).
