The multivariate COX regression analysis of OS showed that, serum TB levels (HR = 3.331, 95% CI: 1.348–8.230, p = 0.009), γ-GT (HR = 2.916, 95% CI: 1.438–5.915, p = 0.003), apoE2 (HR = 6.140, 95% CI: 2.543–14.83, p = 0.00005), and apoE4 (HR = 7.001, 95% CI: 1.620–30.25, p = 0.009) in IHC staining were independent prognostic factors for OS (Table 2). Here, APOE is linked to tuberculosis.
