Clustering of samples from C, S and SD groups using the binary Euclidean distance metric. (A) The 3D PCoA plot shows the spatial distribution of samples of the groups: controls (C - red circles), smokers/drinkers (SD - blue circles) and only smokers (S - green circles) using the coordinates generated by the binary Euclidean distance metric. (B) A cladogram of all samples of the three groups produced by neighbor joining of the binary Euclidean distance matrix.
