Fig 2. UniFrac Principal Coordinate (PCoA) and UniFrac distance analyses for HC40 and MS20 subjects.

Fig 2

(a, c) Open and closed circles indicate individual subjects from HC40 and MS20, respectively. (a) The two components of the unweighted PCoA plot explained 6.96% and 4.30% of the variance. ANOSIM statistic, R = 0.239, P ≤ 0.0009. (b) Mean unweighted UniFrac distances for HC-HC, HC-MS, and MS-MS subjects. (c) The two components of the weighted PCoA plot explained 18.44% and 9.86% of the variance. ANOSIM statistic, R = 0.208, P ≤ 0.002. (d) Mean weighted UniFrac distances for HC-HC, HC-MS, and MS-MS subjects. (b, d) Error bars represent standard deviations of the UniFrac distances between samples. *P ≤ 0.05.
