Development of Estimate Formulas for Appendicular Lean Mass Using Forearm Circumference in Older Adults Requiring Care.
Article in Journal of frailty, sarcopenia and falls, 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
Objectives: The use of forearm circumference (FC) in the estimation equation to predict appendicular lean mass (ALM) in older adults who require care remains unclear. Methods: This cross-sectional study targeted 132 participants aged ≥65 years requiring care. The ALM was measured with bioelectrical impedance analysis (BIA). Handgrip strength (HS) was measured with a digital hand dynamometer. FC was measured at the site of maximum swelling using a tape measure. Multiple regression analysis was conducted to develop an equation for estimating BIA-measured ALM using FC. Moreover, we investigated a systematic error by Bland-Altman analysis between BIA-measured ALM and ALM calculated by the estimation equation. Results: We developed the four estimation equations. The values of r, adjusted R Conclusions: This study developed the formula using FC, which can predict ALM with less influence of edema, but it may over- or underestimate ALM in older adults requiring care.
