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

objectivesThe aim of this study was to investigate associations between toe grasp strength (TGS), skeletal muscle mass, and calcaneal bone status in young adults, and to determine whether TGS independently associates with musculoskeletal parameters.

methodsThis cross-sectional study included 150 healthy young adults (118 males, 32 females; median age: 23 years). TGS was assessed using a standardized toe grasp dynamometer. Skeletal muscle mass was measured by bioelectrical impedance analysis (InBody 570), and calcaneal bone status was evaluated using quantitative ultrasound, expressed as standardized speed of sound (s-SOS). Associations between TGS, skeletal muscle index (SMI), and s-SOS were examined using correlation and multivariable regression analyses, with sex-stratified analyses.

resultsSignificant sex differences were observed in TGS, SMI, and s-SOS, with males showing higher values. In males, TGS was positively associated with both SMI and s-SOS. Multivariable analyses showed that higher TGS and younger age were independently associated with greater SMI and s-SOS in males. No significant associations were observed in females.

conclusionsIn males, higher TGS is associated with greater skeletal muscle mass and better calcaneal bone status, suggesting that lower limb muscle strength reflects musculoskeletal status during early adulthood. Longitudinal studies are required to further clarify these associations.
