Fig. 2From: Sputum bacterial load and bacterial composition correlate with lung function and are altered by long-term azithromycin treatment in children with HIV-associated chronic lung diseaseBoxplot of bacterial load between trial arms at each visit (A) and between visits within AZM arm only (B) and placebo arm only (C). 16S rRNA gene copy number, used as proxy for total bacterial load, was measured with qPCR. The between arm comparisons were implemented using Wilcoxon signed rank test for unpaired samples whilst within-arm comparisons used Wilcoxon signed rank test for paired samplesBack to article page
