Association of neutrophil-to-lymphocyte ratio and CRP with spirometry in COPD patients in North India

This study concludes that the FEV1, FVC, and FEV1/FVC ratio were lower in severe COPD patients, and it also reveals that individuals with severe COPD have elevated levels of serum CRP and N/L ratio, which correlates with the severity of COPD. Elevated N/L ratio and CRP level may be used as non invasive predictors and cost-effective tools for COPD patients at the Primary health centre level for screening of the severity of COPD patients.
