Association between pubertal timing and bone and body composition in young adult men.
Observational study in Scientific reports, 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
Bone and muscle development are important processes in pubertal maturation. The aim of this study was to investigate associations between pubertal timing and bone density and body composition in young adult men. In this observational study, bone and body composition was cross-sectionally assessed by dual-energy X-ray absorptiometry in 2056 healthy young men with median age 19, who retrospectively self-reported if they experienced pubertal changes at an earlier, similar or later age than their peers. Associations between voice break timing and bone and body composition were analyzed by linear regression. Men reporting earlier voice break than their peers (n = 417, 20%) had higher lumbar bone mineral density (BMD) and higher total body BMD. Apart from higher BMI, there were no differences in body composition. Men who reported later voice break (n = 353, 17%) had lower lumbar bone mineral content, bone area and volume, but similar BMD. They had lower BMI, lean mass and fat mass, resulting in a lower fat-to-muscle ratio. In conclusion, even after adult height has been reached, physiological variations in pubertal timing were associated with differences in bone and body composition in young adult men.
