Fig. 6From: Comparison of the salivary and dentinal microbiome of children with severe-early childhood caries to the salivary microbiome of caries-free childrenHierarchical clustering of microbiota data at bacterial species level. Abundances are colour-coded according to the colour key on the top left with grey representing a value of zero. Euclidean distance and complete linkage were used to cluster the rows and columns of the heatmap. The colour bar on top of the heatmap is coloured according to sample type: CAC red, CAS green and CFS blue. All taxa present with at least one species with a median value ≥0.5% in all three groups are includedBack to article page
