The clinical value and application of augmented reality navigation in brachial plexus schwannoma.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
This study aimed to introduce the application of magnetic resonance imaging (MRI)-derived augmented reality (AR) navigation in the surgical treatment of brachial plexus schwannomas and to evaluate and statistically analyze their clinical outcomes. Preoperative MRI data were converted into 3D reconstructions and AR holograms. Using mixed-reality glasses, surgeons employed these reconstructions for intraoperative tumor localization and surgical planning. Outcomes were assessed through structural visualization metrics (tumor, arteries, veins, and nerves) and clinical parameters (incision length, operative time, intraoperative blood loss, postoperative complications, satisfaction, and Quick-DASH scores). Twelve patients (mean age 44.75 ± 3.76 years) successfully underwent tumor resection. Compared to conventional MRI, AR demonstrated superior visualization of tumors (p < 0.0001), arteries (p = 0.0004), veins (p < 0.0001) and nerves (p < 0.0001). Although there was no significant change in incision length, intraoperative blood loss and Quick-DASH, AR navigation significantly reduced operative time (p = 0.04) and improved satisfaction score (p = 0.03). AR navigation enables intuitive surgical planning to circumvent critical neurovascular structures, thereby enhancing procedural safety for brachial plexus schwannoma resection, which makes it a promising adjunctive technique.
