Investigation of the cortical bone metabolome of C57BL/6J mice with adenine-induced kidney disease.

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
The loss of bone fracture resistance in CKD results from both a loss of bone mass and decreased bone material properties, which together result from changes to the health and activities of bone cells. Determining changes to bone tissue metabolism with CKD may reveal insights important to monitoring and mitigating the decrease in bone fracture resistance with this disease. In this study, untargeted metabolomics was conducted on marrow-flushed cortical tibiae from female and male C57BL/6J mice fed either control or 0.2% w/w adenine diets for 3.5 or 7 wk. Liquid chromatography mass spectrometry assessed metabolites from tibia extracts. Group comparisons (adenine vs control, 7 wk vs 3.5 wk, female vs male) were conducted using principal components analysis and partial least squares discriminant analysis. Clusters of metabolites were also assessed using ensemble clustering with cluster optimization analysis. Volcano plots and variable importance in projections (VIP) scores identified metabolites that differed between groups, and pathway analyses were conducted using these features. Adenine-induced CKD produced few differences in cortical bone tissue metabolism, based on the comparison of pooled adenine vs control groups. However, pantothenate and Coenzyme-A biosynthesis, along with essential and nonessential amino acid pathways, registered notably high VIP scores for adenine vs control comparisons. There were many significant differences between 3.5- and 7-wk treatment groups (adenine and control). The pathways different between diet lengths for control mice reveal potential effects of skeletal aging. However, there were significant changes in the pentose phosphate pathway and cysteine metabolism between 3.5- and 7-wk adenine diets, indicating an effect of CKD severity. While sex differences in this study were modest, there was greater separation between female adenine vs control groups compared to male adenine vs control groups, indicating potential sex differences in the impacts of CKD on bone tissue metabolism.
