Relationship between sputum hBD-2 levels and the pathogen colonization status (Only Bact+, Only Vir+, Both+, Both-) in exacerbations. (A) The relative change in sputum hBD-2 level from baseline to exacerbations was calculated as per status. The relative change in sputum hBD-2 level was compared among patients according to the status at baseline. (B, C) The sputum hBD-2 levels were compared at the time of exacerbation, and (B) relative change in sputum hBD-2 level (C) was compared in patients according to the colonization status at the time of exacerbation. Statistical methods: Kruskal-Wallis test was used to determine significance (for more details about Fig. 4, see Additional file 1: Table S6)
