Abstract Background Although COPD among non-smokers (NS-COPD) is common, little known about this phenotype. We compared NS-COPD subjects with smoking (S-COPD) patients in a rural Indian population using variety of clinical, physiological, radiological, sputum cellular and blood biomarkers. Methods Two hundred ninety (118 healthy, 79 S-COPD, 93 NS-COPD) performed pre- post-bronchodilator spirometry were followed for 2 years to study the annual rate decline lung function.
