Comparison of clinical presentation and treatment response among youth with atypical anorexia nervosa and anorexia nervosa.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectiveAtypical anorexia nervosa (AAN) is an eating disorder that shares all symptoms with anorexia nervosa (AN) except "significantly low weight." Here, we aim to further understand the potential similarities and differences between AN and AAN in a clinical sample of patients receiving family-based treatment (FBT) for AN or AAN. The objectives of this study were to 1) compare clinical presentations among adolescent and young adult patients with AN and AAN; and (2) evaluate and compare treatment response to FBT among these patients.
methodClinical data from 1,438 patients (M = 15.3 years, SD = 2.51) undergoing virtual augmented family-based treatment (FBT) who met research specified criteria for AN or AAN were analyzed. To provide the most robust comparison, four common definitions of AAN identified in previous research were retroactively applied to create comparison groups and assess possible differences in symptom presentation and treatment response.
resultsThe percentage of patients classified as AAN ranged from 20%-81.3% depending on definition. Patients with AAN presented with slightly higher eating disorder and depression symptomatology in half of the definitions. All AAN groups gained weight more slowly throughout treatment; other symptom improvement was similar between groups.
conclusionsResults show more similarities than differences in presentation and treatment response among patients with AN and AAN and confirm previous pilot studies showing FBT is effective for AAN. Although currently diagnostically distinct, apparent differences between AN and AAN were not found in this study, suggesting a re-consideration of this diagnostic separation.
