1 · What the graph read from it

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.

2 · The registry

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

backgroundThe simplified AnthropoAge (S-AnthropoAge) has emerged as a useful marker for characterizing aging trajectories and estimating mortality risk. Given the importance of physical attributes like muscle strength, sit-to-stand performance, and gait speed in assessing health and predicting outcomes in older adults, this study investigates the correlation between S-AnthropoAge and these physical performance indicators among older Chinese.

methodsData from participants aged 60 + were drawn from the second wave of the China Health and Retirement Longitudinal Study. Muscle strength was evaluated by recording the highest measurement of handgrip strength (HGS) from the dominant hand. Sit-to-stand performance was assessed by timing the completion of five times sit-to-stand tests (FTSST), and gait speed was measured as the average speed over two 2.5-meter walks. S-AnthropoAge was calculated through an online platform that required inputs chronological age (CA), height, weight, waist circumference and ethnicity. Multiple linear regression analysis was performed to examine the association between S-AnthropoAge and various functional performance metrics.

results5,106 participants were included in the analysis. After covariate adjustment, multiple linear regression models demonstrated that S-AnthropoAge exhibited modestly stronger associations than CA for HGS (males: β = -0.346 vs. -0.276, Δβ = - 0.070; females: β = -0.277 vs. -0.237, Δβ = - 0.040) and FTSST time (males: β = 0.270 vs. 0.240, Δβ = 0.030; females: β = 0.251 vs. 0.235, Δβ = 0.016), though absolute differences were small. For gait speed, both age metrics were significantly associated in males (p < 0.001), though CA showed a slightly larger effect size (β = 0.085 vs. 0.070, Δβ = 0.015). Model fit indices further supported S-AnthropoAge's relevance: adjusted R² values were marginally higher for HGS (males: 0.183 vs. 0.166; females: 0.130 vs. 0.115) and FTSST (females: 0.096 vs. 0.090), while male FTSST models showed equivalent explanatory power (adjusted R² = 0.089 for both). All gait speed models accounted for minimal variance (adjusted R² < 0.01).

conclusionS-AnthropoAge shows modest advantages over CA in correlating with key physical function measures (HGS, FTSST) and may complement CA in assessing functional aging.
