Fig. 3From: Association between high expression of intratumoral fibroblast activation protein and survival in patients with intrahepatic cholangiocarcinomaOS and RFS of the groups with low and high expressions of SMA in the peripheral and intratumoral regions. (a, b) OS tend to be lower in the group with high SMA expression than the group with low SMA expression in the peripheral region, but there was no significance in the RFS (p = 0.279 and p = 0.326, respectively). (c, d) There are no significant differences in OS and RFS between the groups with high and low expression of SMA in the intratumoral region.
