*Compared between the patients with pulmonary infection vs. non-pulmonary.
OR, odds ratio; CI, confidence interval; APACHE-II, Acute Physiology and Chronic Health Evaluation II; HR, heart rate; T, temperature; RR, respiratory rate; OI, oxygenation index; TLC, T-lymphocyte count; NK LC, natural killer lymphocyte count; FI-lab, the Frailty Index based on routine laboratory tests.
P values <0.05 were displayed in bold and considered as independent predictors of 28-day mortality.
