When Food Avoidance Meets Compatible Diagnostic Criteria: Avoidant/Restrictive Food Intake Disorder Features in Irritable Bowel Syndrome.
Article in Neurogastroenterology and motility, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the 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.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundAlone, the Nine Item Avoidant/Restrictive Food Intake Disorder (ARFID) Screen (NIAS) only allows for ARFID-like symptom detection, potentially overestimating its prevalence. We aimed to investigate the prevalence of ARFID-like symptoms and DSM-5-compatible ARFID (based on medical chart review) in irritable bowel syndrome (IBS), and to compare characteristics associated with these definitions.
methodsAdult patients with IBS according to Rome IV criteria, consulting in our tertiary care center between January 2024 and February 2025, were included. Patient data were collected using validated questionnaires, including NIAS-Fr. ARFID-like symptoms were defined as meeting the cut-off for at least one NIAS-Fr subscale (≥ 10 on "picky" or "fear," or ≥ 9 on "appetite"). A medical chart review using our center's clinical data warehouse was conducted for detecting medical impairment and eating disorder (ED) diagnosis. Patients with a positive NIAS-Fr, without ED, and with at least one medical/psychosocial impairment were considered to be in the "DSM-5 compatible ARFID" group. Univariate and multiple logistic regression analyses were conducted. KEY
resultsAmong the 326 included patients, 47.5% had ARFID-like symptoms, and 33.4% met DSM-5-compatible criteria for ARFID. Functional dyspepsia (FD) was prevalent in 60.4% of patients. Depressive symptoms, somatic symptom severity, and FD were independently associated with having ARFID-like symptoms (Nagelkerke R CONCLUSIONS AND INFERENCES: ARFID-like symptoms were more prevalent than DSM-5-compatible ARFID in our population. Applying DSM-5-compatible criteria was associated with more severe gastrointestinal and depressive symptoms. Standardized DSM-5 ARFID assessment methods remain to be established.
