Inflammatory indicators, including the systemic immune-inflammation index (SII), neutrophil-to-lymphocyte ratio (NLR), and neutrophil percentage-to-albumin ratio (NPAR), also demonstrated predictive value for SAP risk, particularly NLR, which was significantly elevated within 24 h after ischemic stroke and correlated with pneumonia severity. The gene discussed is ALB; the disease is ischemic stroke.
