Fig. 1From: Prevalence and abundance of selected genes conferring macrolide resistance genes in COPD patients during maintenance treatment with azithromycinRelative changes in gene abundance at 6 and 12 months after treatment with placebo or azithromycin. Changes related to baseline gene abundance of mefA (a, b), ermF (c, d) and ermB (e, f) at 6 and 12 months are shown. Results are visualized in box-plots with median and 10th and 90th percentiles (dots show outliers). The dotted line shows the zero line. Mean logs ratio and statistics are shown in Table 4Back to article page
