Fig. 6From: Suppressor of variegation 3–9 homologue 1 impairment and neutrophil-skewed systemic inflammation are associated with comorbidities in COPDBlood neutrophil and eosinophil counts are not significantly related to moderate to severe COPD exacerbations. WBC and differential counts in COPD patients with 0–1 moderate to severe exacerbations in the past 1 year (non-AEr) were compared with those in patients with ≥ 2 moderate to severe exacerbations in the past 1 year (AEr) by statistical analysis. a The peripheral blood WBC counts were similar in COPD subjects with few exacerbations annually (non-AEr) and those with frequent exacerbations (AEr). p = 0.078. b Neutrophil counts were also similar in both groups. p = 0.061. c Eosinophil counts were not different between the groups. p = 0.570 (d) The ratio of peripheral blood eosinophils/neutrophils was similar in both groups. p = 0.397. n.s.: not significantBack to article page
