Association of Elevated Serum GM-CSF, IFN-γ, IL-4, and TNF-α Concentration with Tobacco Smoke Induced Chronic Obstructive Pulmonary Disease in a South Indian Population

Figure 1

Serum concentrations of granular macrophage colony stimulating factor (GM-CSF) and corresponding correlation with lung function parameters among long-term smokers with or without chronic obstructive pulmonary disease (COPD). (a, b) GM-CSF concentrations were increased in TS COPD group compared to TS CONTROL group (p=0.014); inverse correlation of GM-CSF concentrations to (c) FEV1/FVC and (d) and was detected in the study cohort. Data is presented as median (25th-75th percentile); TS COPD: n=30 and TS CONTROL: n=20; p<0.05 was considered as statistically significant. COPD: chronic obstructive pulmonary disease; FEV1/FVC: forced expiratory volume 1 second /forced vital capacity; : forced expiratory volume 1 second prebronchodilator challenge; : FEV1 postbronchodilator challenge; TS COPD: tobacco smokers with COPD; TS CONTROL: tobacco smokers without COPD.
