Adaptation and Validation of the Gastroesophageal Reflux Disease Questionnaire (GerdQ) for Arabic-Speaking Populations.
Article in Cureus, 2026. 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
objectiveThe objective of this study was to translate, adapt, and validate the Gastroesophageal Reflux Disease Questionnaire (GerdQ) in Arabic.
methodThis study involved translating the original English version of the GerdQ into Arabic. A cross-sectional study design was employed utilizing an online Google Forms (Google LLC, Mountain View, California, United States) survey distributed across 22 Arabic-speaking countries.
resultsA total of 201 participants with a mean age of 23.94 ± 8.03 years from various Arabic countries completed the questionnaire. Of these, 145 participants were female (72%). The Arabic version of the GerdQ demonstrated excellent reliability, with an internal consistency of 0.86. The test-retest reliability of the questionnaire over the two-week interval was 0.92. The Comparative Fit Index (0.96), Tucker-Lewis index (0.94), and other incremental fit indices were all above the 0.95 threshold, which is indicative of good fit. The questionnaire demonstrated moderate diagnostic performance for detecting GERD (area under the curve (AUC) = 0.67). An optimal cutoff score of 10 maximized the sensitivity, specificity, and other metrics.
conclusionThe newly adapted Arabic version of the GerdQ is anticipated to enhance the effectiveness of this tool in both research and clinical settings within Arabic-speaking regions, facilitating better understanding and management of gastroesophageal reflux disease.
