1 · What the graph read from it

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.

2 · The registry

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

Bone regeneration requires innovative solutions to enhance osteogenic differentiation and support effective tissue repair. This study presents a novel approach to bone tissue engineering by developing peptide-functionalized nanofibrous scaffolds (NFS). The fabrication of a blended hyaluronic acid (HA) and polydopamine (PD) scaffold functionalized with bone marrow mesenchymal stem cells (BMSCs)-affinity peptides (AP) designed to control magnesium ion (Mg) release, which supports BMSCs' osteogenic differentiation and bone regeneration. Characterization studies, including fourier-transform infrared spectroscopy (FTIR) and morphological analysis, confirmed the hydrophilic properties of HA/PDNFS@BMSCs-AP scaffolds, which enhance cell adhesion and proliferation. In vitro and In vivo assessments revealed that the scaffolds significantly promote osteogenesis through AP-induced pathways such as extracellular signal-regulated kinase pathway (ERK) and Phosphatidylinositol 3-kinase (Akt),. Animal model experiments demonstrated accelerated bone repair, supporting the potential of HA/PDNFS@BMSCs-AP scaffolds for targeted bone defect healing. These findings highlight the promise of functionalized nanofibrous scaffolds in bone tissue engineering and their potential application in regenerative medicine and translational research.
