Fig. 2. Overall microbiome of sputum. The relative abundance of bacterial taxa identified in different sputum samples was represented as stacked bar plots. Each bar represents an individual and each colored box, a bacterial taxon, family and phylum. The height of a colored box represents the relative abundance at various taxonomic levels as indicated. HC: Healthy controls; NTM: Women with NTM lung disease only; NTM-BCa: Women with both NTM lung disease and breast cancer. A minimum average abundance of 0.05% was considered for calculating the overall taxa abundance.
