From: The fecal microbiota as a biomarker for disease activity in Crohn’s disease
PCA plots based on the proximity matrix from the fecal samples (N = 164) of the training set using the 50 most discriminant OTUs.
Samples show a clear separation for active versus remission based on the 50 pre-selected OTUs (a), while no separation was observed for use of biologicals (b), mesalazines (c), thiopurines (d), disease location (e) colectomy (f), and age (g).
