Causal relationship between serum creatinine levels and bone mineral density: A Mendelian randomization study.
Article in Medicine, 2026. 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
To study serum creatinine (Scr) levels and bone mineral density (BMD), we used Mendelian randomization (MR) to investigate the causal relationship between them. The genetic association data of Scr levels and total body BMD across age groups were retrieved from the genome-wide association studies, and the causal relationship between Scr levels and BMD was analyzed using the inverse-variance weighting method, MR-Egger regression method, weighted median estimation method, simple mode, and weighted mode. The results of the inverse-variance weighted method indicated that the creatinine level might be a protective factor for the 45 to 60 age group (P = .005, odds ratio = 1.176, 95% confidence interval = 1.049-1.318). All error lines in the sensitivity analysis graph of the retention method were on the right side of 0, suggesting that the results were highly stable and that the MR results were stable, and no association was found in other age groups. Scr levels exhibited a causal relationship with BMD. As a standard proxy indicator for skeletal muscle mass, Scr levels are correlated with BMD. Reduced Scr levels may indicate sarcopenia, which adversely affects skeletal health. Consequently, monitoring Scr could enable the early identification of individuals at risk of low BMD.
