Prognostic significance of Fibulin-5 in HCC cases. Kaplan-Meier 5-year A) overall and B) disease-free survival curves of HCC patients according to the level of Fibulin-5 protein expression. The Fibulin-5 high expression group (>0.31, n = 30); Fibulin-5 low expression group (<0.31, n = 56). The mean expression value obtained for Fibulin-5 of the 86 HCC samples detected by Western blot was chosen as the cutoff value. *P < 0.05 by log-rank test.
