Predictors of Complications in Anorexia Nervosa and Atypical Anorexia Nervosa: Degree of Underweight or Extent and Recency of Weight Loss?
Article in The Journal of adolescent health : official publication of the Society for Adolescent Medicine, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 45 papers, 3 of them syntheses 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
purposeAdolescents with atypical anorexia nervosa (AAN) can experience severe physical complications despite not being underweight, posing questions about the contribution of weight loss to complications experienced in restrictive eating disorders (EDs). This study compared total weight loss and recent weight loss with admission weight as predictors of physical and psychological complications.
methodsRetrospective (2005-2010) and prospective (2011-2013) studies were undertaken of 12- to 19-year-old hospitalized adolescents with anorexia nervosa (AN) or AAN, defined as meeting criteria for AN except underweight (≥85% median body mass index). Predictors were total weight loss (from lifetime maximum), recent weight loss (past 3 months), and admission weight. Outcomes were hypophosphatemia, clinical, anthropometric, and psychometric markers during admission.
resultsIn 171 participants (AN, 118 [69%]; AAN, 53 [31%]), there was little evidence of an association between weight measures and hypophosphatemia. Greater total weight loss (regression coefficient [Coeff]: -1.70, 95% confidence interval [CI]: -2.77, -.63, p = .002) and greater recent weight loss (Coeff: -3.37, 95% CI: -5.77, -.97, p = .006), but not admission weight, were associated with a lower pulse rate nadir. Greater total weight loss (odds ratio [OR]: 1.70, 95% CI: 1.19, 2.24, p = .003) and greater recent weight loss (OR: 2.12, 95% CI: 1.11, 4.02, p = .02) were also associated with a higher incidence of bradycardia.
conclusionsIn adolescents with restrictive EDs, total weight loss and recent weight loss were better predictors than admission weight of many physical complications. This suggests that future diagnostic criteria for AN place greater emphasis on weight loss.
