Risk factors of COPD exacerbations. Adjusted odds ratio of (a) viral infections (b) bacterial abundance (top/bottom quartile) and (c) demographics and clinical history features to be associated with acute exacerbation events or patients with frequent exacerbations (≥2 events/ year). Significance are presented in red (positive association) and green (negative association). Orange dots represent non-significant odds ratio. Horizontal bars represent the 95% confidence interval. Genera names are in bold and species italicized
