Differential abundance
Only 450 ASVs remained, after considering the ASVs presented in \(\geq\)5% of all samples. At the family level, only Carnobacteriaceae (Adjusted p-value=0.033), and at the genus level, bothGranulicatella (Adjusted p-value=0.021) andAggregatibacter (Adjusted p-value=0.011) showed significantly higher abundance in the MDI group compared to the DPI group (Figure 5).
