Detection of HDGF protein in HCC and Kaplan-Meier plots of overall survival duration in patients with HCC. HDGF protein expression in HCC and normal liver samples. A and B. Strong expression of HDGF in HCC samples. C. Weak expression of HDGF in HCC samples(original magnification 400×). D. Negative expression of HDGF in liver sample; E. Kaplan-Meier survival analysis of overall survival duration in 137 HCC patients according to HDGF protein expression. The log-rank test was used to calculate p values.
