Neutrophil-to-lymphocyte ratio on admission is an independent risk factor for the severity and mortality in patients with coronavirus disease 2019

Abstract

• The level of NLR on admission could be an independent risk factor for the severe disease and the mortality of COVID-19. • The predictive value of NLR for poor prognosis was more significant in patients without other potential risk factors. • NLR could help physicians rapidly identify high-risk patients and adopt timely intervention.
