Regular walking is associated with greater lumbar spine bone mineral density in elderly men with adequate vitamin D levels.
Article 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
Sport practices play a major role in reducing age-related bone loss and preventing osteoporosis and associated fractures in later life. Normal vitamin D levels are crucial in maintaining bone mass and reducing bone turnover, especially in elderly adults. This study investigates whether regular walking combined with normal vitamin D3 levels improves areal bone mineral density (aBMD) and bone mineral content (BMC) at weight-bearing and non—weight-bearing bones in older men compared to controls. Sixteen individuals who walked regularly (8–12 h/week) and fourteen controls (less than 2 h/week) aged between 60 and 75 years were recruited. Bone parameters (aBMD, BMC) were assessed using dual-energy X-ray absorptiometry (DXA), bone turnover and various hormonal markers were measured. vitamin D3 levels were higher in walkers than controls, other hormonal and bone markers did not show any significant differences between the two groups. Walkers exhibited greater BMC and aBMD in the total hip, lumbar spine, dominant upper limb, and dominant and non-dominant whole and distal radius. However, exclusively the lumbar spine aBMD remained significantly higher in walkers after controlling for vitamin D3 levels and total sports participation. These findings suggest that regular walking may be associated with enhanced lumbar spine bone mineral density and maintained bone health in this vulnerable population. providing a strong argument for making such activities easily accessible.
