Protocol for a pilot feasibility randomised controlled trial of fecal microbiota transplantation for adolescent anorexia nervosa.
Article in BMJ open, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06593366 (A Pilot Feasibility Randomized Controlled Trial of Fecal Microbiota Transplant for Adolescent Anorexia Nervosa), which is not on this map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract
introductionDespite its serious impact, anorexia nervosa (AN) remains one of the least understood mental illnesses, with significant gaps in effective treatment options. No medications have been deemed effective and only 50% of individuals respond to conventional psychotherapies. Gastrointestinal (GI) bacteria have been found to be altered in individuals with AN. While, Fecal microbiota transplantation (FMT) has shown potential for alleviating anxiety and depression, its effects remain understudied for individuals with AN. This study aims to determine whether oral capsular FMT is acceptable to adolescents with AN and results in clinical improvement in weight and/or psychological symptoms.
methodsThis study will randomise 20 adolescents with AN, ages 12-17 years, to receive either FMT or placebo capsules. These 20 youth, as well as an additional 10 youth who decline trial enrolment, will participate in qualitative interviews. We will track recruitment rates and collect psychological and biological measures (blood, stool, urine and saliva) at multiple timepoints to assess how gut microbiota and their metabolites may influence the symptoms of AN. Interviews with participants and caregivers will explore their experiences and views on FMT as a treatment approach. ETHICS AND DISSEMINATION: This study has received ethics approval by the Hamilton Integrated Research Ethics Board (#17493) and investigational drug approval by Health Canada (Dossier ID: c292423). Informed consent will be obtained by research staff from all participants. Findings will be disseminated through academic conferences, clinical forums and partnerships with advocacy organisations to reach clinicians, researchers and individuals with lived experience. TRIAL REGISTRATION NUMBER: NCT06593366.
