Studies that test fecal microbiota.

Studies

Open first, then newest update. How each study uses fecal microbiota is read from its arms, and is right about nine times in ten. Ask us to read each study. These are the studies that list it as an intervention; a search of ClinicalTrials.gov also finds studies that mention it only in a description, such as earlier treatment.
