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
backgroundEffective bone-cartilage integration remains a challenge in orthopedic surgery. Conventional methods often fail to reconstruct the native osteochondral interface. This study explores a scaffold-mediated approach utilizing co-cultured osteoblasts and chondrocytes, with platelet-rich plasma (PRP) as a potential promotor for bone-cartilage interface healing.
methodsWe developed a co-culture system integrating both osteoblasts and chondrocytes on PLGA scaffolds, either with or without PRP supplementation. Cell phenotype maintenance was evaluated by RT-PCR, while morphological analysis was performed by scanning electron microscopy and fluorescence microscopy. To assess healing potential, we created a gap-mimic construct comprising bone, scaffold, and cartilage layers, which was implanted subcutaneously in BALB/c-nude mice. Gap healing was evaluated at 4 and 8 weeks through macroscopic examination, quantitative adhesion analysis, and histological assessment of cellular invasion.
resultsCo-cultured osteoblasts and chondrocytes maintained their phenotypes on PLGA scaffolds, with PRP significantly enhancing cell adhesion (215% increase for chondrocytes, 120% for osteoblasts) and proliferation. In vivo, cell-containing scaffolds demonstrated significantly greater attachment at the bone-cartilage interface compared to acellular constructs. PRP-treated scaffolds exhibited higher attachment rates (82.3% vs 76.7%) and cellular invasion (5/6 vs 3/6 constructs) at 8 weeks, with invasion observed as early as 4 weeks in the PRP group, suggesting accelerated remodeling.
conclusionThis study demonstrates the feasibility of developing transplantable scaffolds containing co-cultured osteoblasts and chondrocytes while preserving their phenotypes. These scaffolds exhibit significant potential in promoting healing at the bone-cartilage interface, with PRP further enhancing proliferation and improving the scaffold's ability to promote bone-cartilage interface healing.
