Figure 5From: Identification of the collagen type 1 alpha 1 gene (COL1A1) as a candidate survival-related factor associated with hepatocellular carcinoma Overall survival curves for down-regulated and up-regulated cases of COL1A1 mRNA expression in tumor tissues. Red line: down-regulated (n = 13). Blue line: up-regulated (n = 35). According to the log-rank test, down-regulated cases were significantly correlated with poor overall survival (P = 0.013).Back to article page
