Despite the extensive improvement in antibiotic treatment and medical care, severe adult community-acquired pneumonia (CAP) remains as the significant cause of death worldwide. Earlier prognosis assessment and timely treatment in adult CAP patients are useful for prognosis. The neutrophil-to-lymphocyte ratio (NLR) in blood routine has a broad application possibility in assessing inflammatory reaction and prognosis. The aim of this study was to examine the relationship between NLR and inflammatory reaction and to unravel the usefulness of NLR in the assessment of clinical outcomes in adult CAP patients. ⋯ NLR is a simple, cheap, and rapidly available measurement in blood routine and is associated with unfavorable clinical outcomes in adult CAP patients.
