From: Low human beta-defensin-2 levels in the sputum of COPD patients are associated with the risk of exacerbations

Fig. 3

At baseline, the sputum hBD-2 levels were subdivided by colonization status (Only Bact +, Only Vir +, Both +, Both-) and disease severity (GOLD 0, 1, 2, and 3–4). The sputum hBD-2 levels of COPD patients (A) and controls (B) were compared according to the colonization status. (C) The sputum hBD-2 levels in controls and COPD patients (Bact + or/and Vir +) were compared according to the disease severity. Statistical methods: Kruskal-Wallis test was used to detect significance (for more details about Fig. 3, see Additional file 1: Table S5)
