Development and Validation of a Pediatric Celiac Disease-Specific Quality of Life Measure.

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
introductionQuality of life (QOL) is critical in screening and management of chronic medical conditions, including celiac disease (CD). The aim of this project was to develop a CD-specific pediatric QOL measure (Celiac Disease Life Inventory of Family Experiences [CDLIFE]) with parallel self-report and parent-report forms by generating items through concept elicitation interviews, iterative refinement using cognitive debriefing interviews, and evaluating its psychometric properties and validity.
methodsConcept elicitation interviews were conducted to develop items (9 youth ages 8-19 years with CD; 10 parents of youth with CD), followed by cognitive interviews with additional stakeholders (3 youth with CD, 3 parents, and 8 clinicians) and item administration (parent/youth reports: n = 103/102). Analyses included response frequencies, internal consistency reliability, exploratory factor analyses, and correlations with related measures (Patient-Reported Outcomes Measurement Information System, Pediatric Quality of Life Inventory, and Gluten-Free Diet-Visual Analog Scale).
resultsFrom concept elicitation interviews, 42 youth and 45 parent items were developed. Cognitive debriefing interviews yielded 36 refined items. Psychometric analyses identified 15 items to remove due to ceiling/floor effects, poor item-to-test correlations, and youth-parent mismatch or conceptual mismatch. Total score internal consistency was high (αs = 0.89-0.90). A 4-factor model solution had the best fit (Social Impact, External Support, Adaptive Vigilance, Eating Behaviors/Adjustment) with a fifth single-item domain (Financial Resources). The final CDLIFE (21 items) total scores correlated with most related measures in expected directions for parent and youth forms. DISCUSSION: The CDLIFE may facilitate insight into CD-specific QOL for youth ages 2-18 years, capturing important dimensions of physical and socioemotional health. Administering the CDLIFE will help identify and track families needing support.
