Waist-to-arm ratio is a simple and effective index for screening the sarcopenic obesity in older adults.
Article in BMC geriatrics, 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
objectiveThe purpose of this study was to evaluate the diagnostic performance of the waist-to-arm ratio (WAR) for screening the sarcopenic obesity (SO) in older adults.
methodsA cross-sectional study was conducted among Korean older adults aged over 65 years. Data were extracted from the Korean National Health and Nutrition Examination Survey (KNHANES) 2023 years. Sarcopenia was defined as handgrip strength < 28 kg for males and < 18 kg for females and appendicular skeletal muscle mass index (ASMI) < 7.0 kg/m
resultsThe accuracy levels of WAR for screening SO (as assessed by area under the curve) were 0.895 in males and 0.771 in females. WAR cutoff values for screening SO were calculated to be 3.44 for males and 3.32 for females. The sensitivities were 100.0% in males and 84.2% in females. The specificities were 71.6% in males and 59.4% in females.
conclusionThe present study demonstrates that WAR was a simple and effective index for screening the SO in older adults in Korea, especially in males.
