Donors’ influence on FMT success. A scatter plot showing the comparison of gut microbiota between donor-recipient pairs at baseline (x-axis, Bray-Curtis dissimilarity index computed) versus the shift in the microbiota community structure of every recipient before and after the FMT (y-axis). The size of filled dots is determined by the sum of ranks linked to the improvement of all metabolic parameters evaluated (blood pressure, fasting glucose and insulin, glycosylated hemoglobin, HOMA-IR, weight loss, and BMI loss) (metabolic health score). Color legend is associated with donor information. Asterisks and size represent the average values of all recipients linked to every donor. Dashed gray line indicates linear correlation based on averaged values (asterisks).
