Fig. 3From: Endotracheal tube microbiome in hospitalized patients defined largely by hospital environmentSampling site defines composition. a PCoA axis 1:2 and 2:3 based on the Bray–Curtis index shows that patient microbiomes differ according to the hospital. Clusters were shown to be significant (p = 0.00199) calculated with ADONIS. b Heatmap of the 13 OTUs with significant differences in abundance found by ALDEx2Back to article page
