Figure 2 Acute exacerbations of COPD in hypogamma-COPD vs normal-IgG-COPD. Black dots: COPD patients with IgG <6.1 g/L, grey dots: COPD patients with normal IgG levels. Black lines indicate median and interquartile range. *Indicates significant difference (p<0.0001, Mann–Whitney test). Hospital adm., hospital admissions; Steroid tr., oral steroid treatments; Antibiotic tr., antibiotic treatments.
Figure 3 COPD admissions in previous year by serum IgG levels. There was a significant non-parametric correlation between number of COPD admissions in the previous year (the year preceding inclusion) and the serum levels of IgG measured upon inclusion (Spearman's test p<0.0001).
Figure 4 Survival after inclusion in hypogamma-COPD vs normal-IgG-COPD. The Kaplan–Meyer plot shows transplant-free survival of all included patients from time of inclusion to five years after inclusion of the last patient. Black line: normal-IgG-COPD. Dotted line: hypogamma-COPD. Survival compared using Log-rank test (p=0.0003).
