Exploring markers of feasibility for a pragmatic study of biomarkers in adolescents with eating disorders: steps towards a precision psychiatry approach.

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
objectiveTo examine markers of feasibility for a pragmatic interdisciplinary multi-axial study of biomarkers in adolescents with eating disorders (EDs).
methodThe study included the collection of medical and clinical variables, psychometric measures, dietary logs, sensory and sleep assessments, and biological samples (i.e., blood and stool collection) for biomarker analyses. Adolescents between the ages of 11 to 17 diagnosed with a restrictive ED, along with control participants were enrolled between November 2021 to July 2024. Participants with EDs underwent concurrent treatment while enrolled in the study. Time points for low-weight patients included baseline, 4, 12, and 26 weeks, depending on the biological marker. Control subjects and patients over 90% treatment goal weight were assessed once. Feasibility was evaluated using clinical participant recruitment efficiency and uptake, adherence to the study protocol, rates of study completion, and self-reported ratings of acceptability.
resultsIn total, 100 participants with an ED, and 52 controls participated. We observed high rates of clinical participant enrolment, high adherence with most protocol collection procedures, modest dropout for longitudinal clinical participants (17% at 12 weeks), and positive feedback returned on surveys. We observed higher dropout at the 26-week timepoint (33%). Food log and sleep assessments were hindered by several contributing factors, resulting in completion rates of 31-70% and 40-87%. DISCUSSION: Overall, results suggest acceptable feasibility for most variables assessed. Protocols requiring participation beyond 12 weeks, and utilizing dietary logs and sleep assessments, should be powered accordingly to account for lower completion rates. Further studies are needed to determine methods to optimize dietary and sleep assessments. This study provides valuable insights that can inform future precision psychiatry ED research strategies.
