Muscle mass adjustment for body size: is using a ratio doing the job? A cross-sectional study in two samples of older adults.
Article in European geriatric medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
purposeThe aim of this cross-sectional study was to investigate the prevalence of low muscle mass using different ratios, across categories of BMI in older adults.
methodsMuscle mass estimates obtained by DXA, CT, and BIA from two samples of older adults were used (the Health, Aging, and Body composition study, USA and the MUSCLE study, Japan). For each muscle mass estimate, three ratios were calculated: muscle mass divided by body height squared, muscle mass divided by body weight, and muscle mass divided by body mass index. The prevalence of low muscle mass (ratio < 20th percentile of the sample) was determined across BMI categories.
resultsFor all three ratios, the prevalence of low muscle mass was dependent on BMI. These findings were consistent for the different body composition methods, men and women, and for the two data samples.
conclusionRegardless of the muscle mass-body size ratio being used, cut-off values for low muscle mass need to be BMI-specific.
