Dietary assessment methodologies in eating disorders: a pilot comparative validation study exploring the diet history method.
Article in Journal of eating disorders, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveDietary intake and sub-optimal nutrition have a significant impact on clinical risk, outcomes and mortality in people with an eating disorder. Despite the range of dietary patterns and nutritional issues, there is limited evidence to guide effective use of dietary assessment methods. The aim of this pilot study was to examine the validity of the diet history against routine nutritional biomarkers in female adults with an eating disorder attending a regional outpatient service.
methodThis secondary data analysis utilised demographics, nutrient intakes from diet history and nutritional biomarker data. Spearman's rank correlation, simple and quadratic weighted kappa statistics and the Bland-Altman method were used to explore validity of the diet history compared to nutritional biomarkers.
resultsThirteen female participants (median age 24 years; median BMI 19 kg/m
conclusionsThis pilot study suggests the diet history may be useful for assessing dietary intake in people with an eating disorder and highlights the importance of targeted questioning around dietary supplement use. Determining the validity of dietary assessment methods across ages, diagnoses and settings is required.
