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
Objective: This study aimed to investigate whether platelet-rich plasma (PRP) obtained from the blood of rats preconditioned with hyperbaric oxygen (HBOP) would enhance the biological activity of PRP and accelerate the healing process of femur fractures in a rat model. Design: PRP was derived from blood samples of healthy rats subjected to either hyperbaric oxygen (hPRP) or normobaric air (nPRP). A closed femur fracture model was established in male Wistar rats, with treatments of hPRP or nPRP administered around the fracture site immediately post-fracture and on days 7, 14, 21, and 28. Growth factor concentrations in hPRP and nPRP were biochemically quantified. Bone healing was assessed weekly by X-ray, while histological and immunofluorescence analyses evaluated inflammatory status, osteoprotegerin (OPG), receptor activator of nuclear factor kappa-B ligand (RANKL) expression, and the presence of osteoblasts, osteoclasts, and osteocytes during healing. The effects of hPRP and nPRP on MC3T3-E1 preosteoblast migration and proliferation were also tested Results: hPRP showed significantly higher concentrations of growth factors such as activin-A, brain-derived neurotrophic factor, nerve growth factor, Flt-3 Ligand, granulocyte-macrophage colony-stimulating factor, hepatocyte growth factor, and platelet-derived growth factor, compared to nPRP. Conclusions: HBOP enhances the biological activity of PRP and accelerates bone healing in a closed femur fracture model in rats. This study highlights the regenerative potential of PRP when preconditioned with hyperbaric oxygen for use in bone fracture therapy. Significance statement: PRP is widely used in treating bone defects and fractures, but its enhancement through HBOP remains underexplored. Our findings demonstrate that HBOP potentiates the biological activity of PRP, offering promising therapeutic potential for bone fracture healing. The translational potential of this article: Enriching growth factors in PRP through HBOP could significantly improve tissue regeneration, especially in bone healing. The potential of hPRP in clinical applications is highly promising, particularly in orthopaedic surgery, trauma care, sports medicine, and managing bone healing in compromised patients.
