The case for indexing: Echocardiographic dimensions in the Arab Gulf.
Article in Saudi medical journal, 2025. 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
objectivesTo evaluate echocardiographic parameters in young Emirati males and compare them to American Society of Echocardiography/European Association of Cardiovascular Imaging reference ranges, highlighting the need for population-specific or indexed normal ranges. Echocardiographic reference ranges for cardiac dimensions are primarily derived from Western populations, which may not be suitable for smaller-bodied populations, such as Asians.
methodsEchocardiography was performed on 60 healthy Emirati males undergoing military recruitment from September to December 2024. Measurements included left ventricular (LV), aortic, and left atrial (LA) dimensions and volumes. Parameters were indexed to body surface area (BSA) and compared to established Western norms.
resultsLeft ventricular end-diastolic (38-54 mm) and end-systolic dimensions (23-36 mm) were smaller than Western ranges which are 42-58 mm for end-diastolic and 25-40 mm for endsystolic dimensions. Aortic dimensions were also smaller, including the annulus (17-27 mm) and ascending aorta (18-30 mm). Indexed measurements resolved discrepancies, aligning with global standards. Left atrial dimensions (22-41 mm) were comparable to Western norms, while biplane LA volumes (11-30 ml/m²) and 3D volumes (11-28 ml/m²) were lower.
conclusionSignificant differences exist between cardiac dimensions in Emirati males and Western reference ranges. Indexing to BSA addresses these discrepancies, emphasizing the need for indexed ranges to ensure accurate diagnoses and timely interventions, particularly in diverse populations globally.
