A comparative neuropsychological assessment of anorexia nervosa, bulimia nervosa, binge eating disorder and healthy control: a cross-sectional study in female university students.

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
backgroundEating disorder (ED) symptoms are particularly prevalent among young adults. This study aimed to examine the distinct roles of memory function, mental health, and sleep disturbances in university students with different ED diagnostic categories. METHODOLOGY: In this cross-sectional study, 403 female students were allocated to anorexia nervosa (AN, n = 90), bulimia nervosa (BN, n = 53), binge-eating disorder (BED, n = 116), or healthy controls (HCG, n = 144) based on self-reported physician diagnoses consistent with DSM-5 categories. Participants completed the Eating Disorder Examination-Questionnaire (EDE-Q), Memory Functioning Questionnaire (MFQ), Bergen Insomnia Scale (BIS), and Depression Anxiety Stress Scales – 21 (DASS-21) in a single time-point assessment (January and May 2025).
resultsParticipants in the AN and BN groups showed significantly higher levels of depression, anxiety, stress, insomnia, and ED pathology, along with memory dysfunction, compared to the BED and HCG groups (p < 0.001). Depression scores were markedly elevated in AN (mean = 13.8, 95% CI [6.5–8.8]) and BN (mean = 19.2, 95% CI [12.1–14.1]) relative to HCG (mean = 6.1) and BED (mean = 9.7). Similarly, insomnia scores were higher in BN (mean = 35.2, 95% CI [25.1–27.7]) and AN (mean = 26.6, 95% CI [15.5–19.9]) compared to BED (mean = 11.3) and HCG (mean = 8.9). Within-group analyses further revealed that in AN, anxiety, stress, forgetfulness, and weight/appearance concerns were strongly interrelated (p < 0.05), while in BN, insomnia, affective symptoms, and memory dysfunction were tightly linked with overall ED severity (p < 0.05). In the BED group, binge eating behaviors showed significant associations with insomnia, affective symptoms, and cognitive difficulties (p < 0.05).
conclusionED groups—particularly BN and AN—are characterized by co-occurring insomnia, affective symptoms, and poorer perceived memory functioning. Findings support integrated assessments that include sleep and cognition alongside ED psychopathology and may inform individualized interventions. Results should be interpreted cautiously given reliance on self-reported diagnoses and a single-site, female-only sample.
