Table S1 - Steroid Resistance in COPD? Overlap and Differential Anti-Inflammatory Effects in Smokers and Ex-Smokers

Patients were selected from the GLUCOLD cohort [7]; only persistent smokers and ex-smokers were included. All analyses are adjusted for age and sex. Data are expressed as B, p (regression coefficient, p-value); significant data (p<0.05) are presented in bold; FEV1, post, L = FEV1 after salbutamol expressed in liters; PC20 = provocative concentration of metacholine causing a fall in FEV1 of >20%; ‡ Cell counts/10−7 per m2 of subepithelium; § Cell counts×104 per mL. The absolute changes in bronchial cell counts and sputum cell counts were normalized by Ln-transformation.
