A cross-sectional study underlying the sex-stratified associations between muscle strength and bone mineral density among children and adolescents.
Article in BMC pediatrics, 2026. 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
backgroundBone mineral density (BMD) is crucial for evaluating bone health, particularly in the pediatric population. Physical parameters such as lower body strength (assessed by jump tests) and handgrip strength (a marker of musculoskeletal health) have been linked to BMD. This study aims to investigate the association between upper and lower limb strength and BMD of the forearm and femur in children and adolescents stratified by sex.
methodsThis cross-sectional study involved 57 participants (aged 9 ± 2 years) from a philanthropic institution in Brazil. Participants were assessed for anthropometric measurements, somatic maturation, and BMD and lean soft tissue using Dual X-ray Absorptiometry (DXA). Handgrip strength was measured using a dynamometer, and horizontal and vertical jump performances were also assessed. Statistical analyses included Quantile Regression to examine the relationships between strength measures and BMD, adjusted for somatic maturation and lean soft tissue.
resultsSignificant positive associations were found between handgrip strength and femoral BMD, especially in boys (Femoral neck: β = 12.65; 95%CI = 2.39; 22.92,; Trochanter: β = 17.37; 95%CI = 5.04; 29.70; Total femur: β = 11.13 95%CI = 0.98; 21.27).
conclusionUpper and lower limb muscle strength, particularly handgrip and vertical jump performance, were positively associated with BMD of the forearm and femur in children and adolescents with low socioeconomic status, with associations observed in boys.
