Defining "significant weight loss" in atypical anorexia nervosa.
Article in The International journal of eating disorders, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 36 papers, 1 of them a synthesis that pooled it.
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 defined by the symptoms of anorexia nervosa in the presence of "significant weight loss" in individuals who are not underweight. Description of current weight in AAN has been limited, significant weight loss has not been defined, and the distinction between having AAN versus having weight suppression has not been examined.
methodSecondary analyses were conducted with data from an epidemiological study of women (n = 1,640) and men (n = 794). Three definitions of significant weight loss (5, 10, and 15%) for AAN were tested in comparisons with controls and a DSM-5 eating disorder group (DSM-5 ED) on measures of eating pathology and clinical significance using ANCOVA and logistic regression, controlling for age and body mass index. Secondary analyses compared AAN to a weight suppressed group (WS-only) and a cognitive concerns group (COG-only).
resultsAcross weight loss thresholds, ≥25% of adults with AAN were currently overweight/obese. At the 5% and 10% definitions, AAN was associated with elevated eating pathology and distress relative to controls, WS-only, and COG-only in women and men. Women with AAN endorsed less eating pathology and distress than DSM-5 ED at some weight loss definitions, whereas men with AAN did not differ from DSM-5 ED in eating pathology or distress. DISCUSSION: Results support that even a 5% weight loss, combined with cognitive concerns, may produce a group with a clinically significant eating disorder. AAN was observed in both healthy weight and overweight/obese adults, highlighting the importance of screening for restrictive eating disorders at all weights.
