3D Body Scanning-Derived Normative Values of Appendicular Circumferences: A Novel Tool for Sarcopenia Screening in Chinese Adults.
Article in Journal of cachexia, sarcopenia and muscle, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundAppendicular circumferences (ACs) are critical predictors of skeletal health, cardiovascular disease risk and mortality. Currently, comprehensive reference values and associated factors for thigh (TC), calf (CC), upper arm (UAC) and forearm (FC) circumferences remain unestablished in Chinese adults.
methodsThis community-based cross-sectional study (China National Health Survey, April 2023-November 2024) enrolled 8915 adults (≥20 years) for reference value development and 10 632 for association analysis. ACs were measured via 3D scanning, body composition via bioelectrical impedance analysis and handgrip strength using a Jamar dynamometer. Sex-specific centile curves (P2.5-P97.5) were generated using lambda-mu-sigma methods. Propensity score matching balanced age distributions for sex and menopause subgroup comparisons. Multivariate logistic regression was used to examine factors associated with low appendicular circumference (lowest 5th percentile).
resultsMedian (25th and 75th) values for men were TC: 59.27 cm (55.09, 64.18), CC: 39.20 cm (37.17, 41.59), UAC: 28.31 cm (26.75, 30.10) and FC: 27.02 cm (25.67, 28.29); for women, TC: 52.45 cm (49.50, 55.74), CC: 35.71 cm (33.95, 37.76), UAC: 27.71 cm (25.74, 30.10) and FC: 24.64 cm (23.33, 26.07). Age trajectories showed sex-specific patterns: TC, CC and UAC peaked at 20-29 years with subsequent decline, while FC peaked at 40-49 years. BMI-adjusted circumferences exhibited divergent aging trajectories by sex. Postmenopausal women had significantly lower appendicular skeletal muscle mass (ASM), appendicular skeletal muscle mass index (ASMI), handgrip strength and CC than age-matched premenopausal women (all p values < 0.05). All ACs strongly correlated with muscle mass, fat mass and muscle strength (all p values < 0.001), with UAC and FC showing the strongest ASM and ASMI correlations in men (correlation coefficient: 0.757 and 0.735). Factors associated with low ACs included rural residence, lower education, low BMI, elevated body fat (positively linked to low CC, especially ≥ 60 years) and cardiometabolic disorders (diabetes, hypertension, hyperuricemia, dyslipidemia).
conclusionsThis study establishes the first age- and sex-stratified percentile references for ACs in Chinese adults. These results reveal significant sex disparities in absolute and BMI-adjusted measures, providing essential tools for sarcopenia screening, lifestyle intervention evaluation and high-risk population identification.
