ALB and neoplasm: As presented in Table 3 and Table 4, the multivariate Cox regression analysis revealed that PM2.5 ≥ 36 μg/m3 (p = 0.004), Child–Pugh score (p < 0.001), albumin (p < 0.001), macrovascular invasion (p < 0.001), tumor number (p < 0.001), and tumor size (p < 0.001) were significant risk factors for mortality.
