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

Introduction: Bone defects caused by fractures, nonunion, tumors, or infections severely impair patient quality of life. Although autologous bone grafting remains the gold standard, its limited donor availability and additional surgical trauma have driven the development of biomimetic substitutes. Mineralized collagen (MC) replicates native bone extracellular matrix but lacks osteoinductive capacity. Platelet-rich plasma (PRP) is a fibrin matrix enriched with growth factors (e.g., VEGF, PDGF, TGF-β1, IGF-1) that promote cell proliferation and osteoblastic differentiation, yet its gel-like form suffers from poor structural integrity in bone defects. Methods: This study investigated whether the combination of PRP and MC produces enhanced effects on osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs) and healing of critical-sized bone defects. PRP + MC composites were prepared by immersing MC scaffolds in PRP and evaluated using rat BMSCs Results: The PRP + MC composite significantly enhanced BMSC proliferation at day 7. ALP activity and mineralization were markedly increased, accompanied by significantly upregulated RUNX2 expression (∼5.6-fold vs. control). Micro-CT revealed near-complete defect filling with high-density trabecular architecture. Histologically, the composite group exhibited the highest new bone area (∼75%) and OPN expression, with mature lamellar bone and host integration, whereas controls remained dominated by fibrous scar tissue. Discussion: PRP + MC represents a biomimetic and cost-effective strategy for enhancing bone repair. By combining structural scaffolding with biological stimulation, this composite activates RUNX2-mediated signaling and achieves enhanced regeneration in critical-sized defects, supporting its preclinical potential as an alternative to autologous bone grafting.
