Schematic of a Non-metric multidimensional scaling (NMDS) plot. NMDS is an indirect gradient analysis approach which produces an ordination based on a distance and attempts to represent, as closely as possible, the pairwise dissimilarity between objects in a low-dimensional space. Points represent individual participants’ gut microbiota. Participants with gut microbiota that are more similar to one another are ordinated closer together. Circles are confidence ellipses.
