The results of univariate cox analysis showed that the risk of death in the high eIF5A expression group was 6.382 times higher than that in the low eIF5A expression group (HR = 6.382, 95% CI = 2.355–17.297, p < 0.001) (Figure 1(e)), indicating that eIF5A expression might affect the prognosis of CCA. This evidence concerns the gene EIF5A and cholangiocarcinoma.
