The changing landscape of eating disorders between the years 2015 through 2023.
Article in Eating and weight disorders : EWD, 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
purposeDespite the introduction of new eating disorder diagnoses in 2013 with the DSM-5, the characterization of population-level trends and sociodemographic patterns of these expanded eating disorder definitions remain limited. This study examined temporal changes in eating disorder diagnoses and sociodemographic characteristics among adolescents and young adults between the years 2015 and 2023 using the Epic Cosmos database, an aggregate of electronic health records across various healthcare systems.
methodsThis is a retrospective cohort study using Epic Cosmos data, identifying individuals aged 9 years-25 years with an ICD-10 code consistent with an eating disorder diagnosis. Adjusted multivariable regression models assessed temporal changes and associations between sociodemographic characteristics and specific eating disorder diagnoses.
resultsAmong 195,015 individuals, the most common eating disorder diagnoses during the study period were unspecified eating disorder (31%), other specified eating disorder (20%), and anorexia nervosa (20%). Avoidant restrictive food intake disorder had the fastest annual increase followed by binge eating disorder. Significant differences in diagnostic trends were observed by sex, race, ethnicity, and preferred language, with notable increases in avoidant restrictive food intake disorder among females and in anorexia nervosa among Hispanic/Latino and non-English-speaking individuals.
conclusionThe diagnosis patterns of eating disorders are changing, with increases in avoidant restrictive food intake disorder and binge eating disorder as well as changes based on sociodemographic characteristics. These findings highlight the need for improved and continued surveillance of the "newer" eating disorder diagnoses and warrant further investigation for treatment capacity and long-term outcomes. LEVEL OF EVIDENCE: Level V, based on descriptive study.
