FSTL5 and hepatocellular carcinoma: As shown in Figure 2C, FSTL5 expression was positively correlated with prognosis of HCC at TNM stage I/II (n = 95, P < 0.01) (Figure 2C), and there was no significant correlation with the prognosis of patients with HCC at TNM stage III/IV (n = 75, P = 0.43) (Figure 2D).
