Psychometric evaluation of the Dysphagia Symptom Questionnaire for adults and adolescents with eosinophilic esophagitis.
Article in The journal of allergy and clinical immunology. Global, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03633617 (A Phase 3, Randomized, 3-Part Study to Investigate the Efficacy and Safety of Dupilumab in Adult and Adolescent Patients With Eosinophilic Esophagitis), which is not on this map.

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.

Abstract
Background: Eosinophilic esophagitis (EoE) is a chronic, inflammatory disease of the esophagus leading to symptoms of esophageal dysfunction; dysphagia is the most common symptom experienced by adults and adolescents. Objective: We sought to perform a psychometric evaluation of the Dysphagia Symptom Questionnaire (DSQ), a patient-reported outcome measure for patients with EoE. Methods: Using baseline and week 24 data from the randomized, interventional, multinational phase 3 R668-EE-1774 trial (NCT03633617), the measurement properties of the DSQ-including reliability, construct and known-groups validity, responsiveness, and interpretation of change-were evaluated. Results: The analysis population comprised 239 patients with EoE (age [mean ± SD], 28.1 ± 13.14 years; 63.6% male; 90.4% White). Intraclass correlation coefficients of 0.92 and 0.97 exceeded the acceptable reliability threshold (≥0.70). Construct validity correlations with EoE symptom and impact measures were moderate at baseline (| Conclusions: This analysis confirmed that the DSQ has acceptable distributional properties, test-retest reliability, construct validity, and ability to detect change. Therefore, the DSQ is a valid and reliable measure to assess the patient-reported symptom of dysphagia among adult and adolescent patients with EoE in the context of a clinical trial setting.
