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
Age-related osteoporosis is a prevalent bone metabolic disorder distinguished by an aberration in the equilibrium between bone formation and resorption. The reduction in the stemness of Bone Marrow Mesenchymal Stem Cells (BMSCs) plays a pivotal role in the onset of this ailment. Comprehending the molecular pathways that govern BMSCs stemness is imperative for delineating the etiology of age-related osteoporosis and devising efficacious treatment modalities. The study utilized single-cell RNA sequencing and miRNA sequencing to investigate the cellular heterogeneity and stemness of BMSCs. Through dual-luciferase reporter assays and functional experiments, the regulatory effect of miR-183 on CTNNB1 (β-catenin) was confirmed. Overexpression and knockdown studies were conducted to explore the impact of miR-183 and β-catenin on stemness-related transcription factors Oct4, Nanog, and Sox2. Cell proliferation assays and osteogenic differentiation experiments were carried out to validate the influence of miR-183 and β-catenin on the stemness properties of BMSCs. Single-cell analysis revealed that β-catenin is highly expressed in both high stemness clusters and terminal differentiation clusters of BMSCs. Overexpression of β-catenin upregulated stemness transcription factors, while its suppression had the opposite effect, indicating a dual regulatory role of β-catenin in maintaining BMSCs stemness and promoting bone differentiation. Furthermore, the confluence of miRNA sequencing analyses and predictions from online databases revealed miR-183 as a potential modulator of BMSCs stemness and a novel upstream regulator of β-catenin. The overexpression of miR-183 effectively diminished the stemness characteristics of BMSCs by suppressing β-catenin, whereas the inhibition of miR-183 augmented stemness. These outcomes align with the observed alterations in the expression levels and functional assessments of transcription factors associated with stemness. This study provides evidence for the essential involvement of β-catenin in preserving the stemness of BMSCs, as well as elucidating the molecular mechanism through which miR-183 selectively targets β-catenin to modulate stemness. These results underscore the potential of miR-183 and β-catenin as molecular targets for augmenting the stemness of BMSCs. This strategy is anticipated to facilitate the restoration of bone microarchitecture and facilitate bone tissue regeneration by addressing potential cellular dysfunctions, thereby presenting novel targets and perspectives for the management of age-related osteoporosis.
