Abstract

Background: We aimed to accumulate evidence that suggests the potential role of neutrophil-to-lymphocyte ratio (NLR) in determining the prognostic factor for COVID-19 patients. Methods: A cohort of COVID-19 hospitalized patients at the Ilam University of Medical Sciences was analyzed. Logistic regression models were performed to identify the potential role of NLR in determining the prognostic factor for COVID-19 patients. Results: The total number of in-hospital mortality was 43/328 (13.1). Multivariate analysis identified that there was a 26 higher risk of in-hospital death for each unit increase in NLR (Odds ratio OR = 1.08; 95% confidence interval 95% CI, 1.01 to 1.14; p = 0.0147). Multivariate analysis identified that there was an 8% higher risk of in-hospital death for each unit increase in NLR (Odds ratio OR = 1.08; 95% confidence interval 95% CI, 1.01 to 1.14; p = 0.0147). Compared with patients in the NLR < 5 group, the NLR of patients in the NLR ≥ 5 group had a 16-fold higher risk of mortality (OR = 16.04; 95% CI, 1.14 to 224.95; p = 0.0395) after adjustment for potential confounders. Conclusions: NLR is an independent risk factor of mortality COVID-19 patients. © 2021 Verlag Klinisches Labor GmbH. All rights reserved.
