PCA biplot (biodiversity variables and cases) using PCA for groups. OR-CD and OR-UC refer to oral samples collected from CD and UC patients, respectively, whereas FE-CD and FE-UC refer to faecal samples collected from CD and UC patients, respectively, according also to biological activity (FC). The clinical activity is indicated for each point-group as a number at the end of the label. FC levels were categorized according to the range: (1) possible remission FC < 250 mg/kg, (2) grey area FC between 250 mg/kg to 500 mg/kg, and (3) possible clinical activity FC > 500 mg/kg). Arrows indicate the position of the DE, sampling points at disease onset/baseline.
