Characterization of skeletal alterations in a model of prematurely aging mice.
Article in Age (Dordrecht, Netherlands), 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
An age-related bone loss occurs, apparently associated with the concomitant increase in an oxidative stress situation. However, the underlying mechanisms of age-related osteopenia are ill defined since these studies are time consuming and require the use of many animals (mainly rodents). Here, we aimed to characterize for the first time the bone status of prematurely aging mice (PAM), which exhibit an increased oxidative stress. Tibiae from adult (6 months) PAM show an increase in bone mineral density (BMD) and bone mineral content (assessed by bone densitometry) versus those in their normal counterparts (non-prematurely aging mice, NPAM) and similarly decreased in both kinds of mouse with age. However, at this bone site, trabecular BMD (determined by μ-computerized tomography) was similar in both adult PAM and old (18 months) NPAM. Femurs from these groups of mice present an increase in oxidative stress, inflammation, osteoclastogenic, and adipogenic markers, but a decrease in the gene expression of osteoblastic differentiation markers and of the Wnt/β-catenin pathway. Our findings show that adult PAM recapitulate various age-related bone features, and thus are a suitable model for premature bone senescence studies.
