Heatmap of natural log fold changes in abundance of the 26 phyla with an adjusted p < 0.05 for MET_No_Treatment, MET_Treatment, or PUS when compared to control. Red indicates increased abundance in the comparison group versus control; blue indicates decreased abundance in the comparison group versus control. Zero values in white cells indicate non-significant log fold change of abundance (adjusted p > 0.05)
