After applied multivariate COX regression analysis, we found that the higher albumin level (HR = 0.90, 95% CI: 0.81–0.99, P = 0.03) was the independently protective factor, but older age (HR = 1.07, 95% CI: 1.01–1.13, P = 0.02) and CCI score≥3 (HR = 6.77, 95% CI: 1.40–32.69, P = 0.02) were the independent risk factors for 1-year all-cause death in patients with pulmonary TB and type 2 diabetes comorbidity (Table 2). Here, ALB is linked to type 2 diabetes mellitus.
