Figure 2

Bray-Curtis based non-metric multidimensional scaling (NMDS) plot of all samples. NMDS plot (stress 0.22) shows the clear clustering of tongue samples distinct from SubG and SupG samples. Ellipsoids represent a 95% confidence interval surrounding each group. MRPP analysis concluded that the members of the tongue and SubG/SupG groups were more dissimilar than expected by chance (A = 0.06, T = -22.7, P < 0.001).
