Design and usability of Abu Dhabi Food Intake24: a culturally adapted digital 24-hour dietary recall for the United Arab Emirates.

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
Background: Standardized dietary assessment tools are essential for evaluating population diets, eating patterns, and their relationships with health. Although digital dietary assessment tools can support more standardized and efficient dietary data collection, they require appropriate cultural adaptation to be applicable in different populations. In the United Arab Emirates (UAE), the lack of a culturally appropriate digital 24-h dietary recall tool limits standardized dietary assessment for nutrition research and population surveys. Objective: To develop a culturally adapted digital 24-h dietary recall application for the UAE population's eating practices. Methods: Abu Dhabi Food Intake24 (ADINTAKE24) is a tablet-optimized, Android-based application. It collects survey questionnaires and 24-h dietary recall data, calculates nutrient intake, and compares the results with the recommendations. The ADINTAKE24 uses the multiple-pass method that integrates food composition data from the United States Department of Agriculture (USDA), regional, and local sources. UAE-specific food photographs aid in estimating food portion sizes. The application is available in Arabic and English and includes a web-based administrative interface. The system was iteratively developed and tested under field conditions during a large community-based nutrition survey. A pilot survey with families informed system refinement, followed by usability assessment among 35 trained interviewers using the System Usability Scale (SUS). Results: After initial development, the tool was piloted with 98 participants from 39 households using an interviewer-administered approach. Challenges identified during the pilot study included problems with saving and searching for food items in the food composition databases on the server during field data collection. Refinements were made based on the tool's feedback to improve its functionality. The mean System Usability Scale (SUS) score was 69.9 (95% CI: 66.0-73.9; SD = 11.6). Conclusion: Abu Dhabi Food Intake24 addresses a key gap in digital dietary assessment in the UAE. Further usability evaluation of the finalized application and validation for self-administered use are needed before wider implementation.
