EIF5A and cholangiocarcinoma: However, in multivariate cox analysis, eIF5A expression (HR = 19.678, 95% CI = 1.759–220.061, p < 0.05), age (HR = 1.079, 95% CI = 1.001–1.164, p < 0.05), and pT stage (HR = 0.232, 95% CI = 0.058–0.927, p < 0.05) might be independent risk factors for patients with CCA (Figure 1(f)).
