Paired toilet paper and stool samples do not differ in richness, but differ slightly in composition. a Comparison of Shannon alpha diversity between paired stool and toilet paper samples. No significant difference in diversity was observed (paired t test, p = 0.7053). See Additional file 2 Figure S2 for additional alpha diversity measures. b Principal coordinates analysis (PCoA) of Unweighted UniFrac distances computed between paired stool and toilet paper samples from the same individual (see Additional file 2 Figure S3 for additional metrics). Each color represents a single individual and the shapes identify the sample type. A small but significant difference was observed between the community compositions of the two sample types (permanova R 2 = 0.04, p = 0.0017) comparatively to a larger significant difference between paired samples (permanova R 2 = 0.75, p = 0.0001)
