Serum kynurenine levels are a novel biomarker to predict the prognosis of patients with hepatocellular carcinoma
Fig 2
Cumulative survival rates of HCC patients according to the kynurenine levels.
Cumulative survival rates of HCC patients according to kynurenine levels was analyzed using Kaplan-Meier’s method. Black solid, gray solid, and dotted lines indicate stratified kynurenine levels of <600, 600–899, and ≧900, respectively. Incidence rate differed significantly among the three groups by the log-rank test, increasing along with the kynurenine level.
