Figure 2

The overall survival ( OS) of hepatocellular carcinoma (HCC) with and without CK19 expression in regional lymph nodes (LN). The solid line represents LN without CK19 expression and the dashed line represents LN with CK19 expression. The horizontal axis is the survival in months and the vertical axis is the percentile cumulative survival. The median OS was 9.37 ± 3.17 (95% CI 3.165 to 15.575) months for LN with CK19 expression and 28.96 ± 12.92 (95% CI 3.642 to 54.278) months for LN without CK19 expression (P = 0.007). HCC with CK19 expression in regional LN had a worst prognosis in terms of OS.
