Association between hand grip strength and bone mineral density in US adolescents aged 12-19 years: a cross-sectional study.
Article in European journal of pediatrics, 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
objectivePrevious studies have shown that grip strength reflects not only muscle function but also relates to bone mineral density (BMD) in adults. However, its association with BMD in adolescents remains unclear. This study aimed to examine the correlation between grip strength and BMD among US adolescents aged 12-19 years.
methodsData were drawn from the National Health and Nutrition Examination Survey (NHANES) 2011-2014, including 1,752 adolescents aged 12-19 years. Combined grip strength was defined as the sum of the maximum readings from each hand using a hand-held dynamometer. BMD of the right leg, trunk, and whole body was measured using dual-energy X-ray absorptiometry (DXA). Univariate and multivariate linear regression models were applied to assess the relationship between grip strength and BMD.
resultsAfter adjustment for age, ethnicity, body mass index (BMI), smoking status, alcohol consumption, calcium and vitamin D supplementation, and serum calcium and phosphorus levels, grip strength showed a positive association with right leg BMD [β = 0.004, 95% CI: (0.004, 0.004)], trunk BMD [β = 0.004, 95% CI: (0.004, 0.004)], and whole-body BMD [β = 0.003, 95% CI: (0.003, 0.004)] (p < 0.001).
conclusions(1) Grip strength was positively associated with right leg, trunk, and whole-body BMD among American adolescents aged 12-19 years. (2) Hand grip strength may serve as a useful indicator in assessing skeletal health in this age group. WHAT IS KNOWN: • A significant positive association persists between handgrip strength and bone mineral density among adolescents. WHAT IS NEW: • Literature is not avallable regarding sports participation and pubertal status with bone mineral density in adolescents.
