Severity levels of anorexia nervosa and atypical anorexia nervosa in a Korean cohort.
Article in European eating disorders review : the journal of the Eating Disorders Association, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectiveDespite its potential for informing tailored treatments, the severity of eating disorders (EDs) lacks clear conceptualisation. The present retrospective cohort study examined the clinical validity and utility of severity specifiers for anorexia nervosa (AN) and atypical AN in a Korean population.
methodData from 696 Korean outpatients with AN or atypical AN were analysed. Severity criteria for AN from the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, and the Medical Emergencies in Eating Disorders (MEED) guidance were used. Severity criteria applied for atypical AN were the frequency of intermittent fasting (ED Diagnostic Scale item 17), Eating Disorder Examination Questionnaire global scores, and the degree of weight suppression.
resultsPrevalence of extreme cases of AN in our cohort was higher than in Western populations in previous studies. MEED guidance further subclassified extreme AN, revealing distinct psychopathological profiles across severity levels. The proposed severity classification for atypical AN based on the weight loss behaviour of intermittent fasting showed merit.
conclusionsThese findings suggest a potential need for a more nuanced AN severity classification that better represents severe medical aspects and encompasses cultural and ethnic diversities. In atypical AN, there is a need to examine severity indices measuring pathological behaviours.
