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
objectiveThis study aims to introduce an innovative technique for placing pedicle screws in patients with extremely small lumbar pedicles using an oblique view from a C-arm x-ray machine, achieving a comparable gripping force to conventional implanting for the treatment of thoracolumbar vertebral fractures.
methodsA retrospective analysis was conducted on 11 patients with extremely small lumbar pedicles and thoracolumbar vertebral body fractures. The height of the vertebral body and Cobb angle were measured on computed tomography radiographs, and comparisons were made between pre- and postoperative values. Scores from the visual analog scale, Oswestry Disability Index, and Short Form-36 were recorded to evaluate the surgical outcomes.
resultsAll patients successfully underwent the surgery without intraoperative complications such as pedicle collapse, cerebrospinal fluid leakage, or nerve damage. The height of the anterior margin of the vertebral body and the compression rate of the anterior margin of the injured vertebrae showed significant improvement, as did the Cobb angle, with statistically significant differences (
conclusionsThe C-arm x-ray machine oblique radiograph-assisted external pedicle implanting approach offers a simple, accurate, and safe alternative for internal fixation surgery in patients with extremely small lumbar pedicles, without the need for an O-arm navigation system. CLINICAL RELEVANCE: This retrospective cohort study confirms that the technique is a highly effective modality for managing thoracolumbar vertebral fractures with extremely narrow lumbar pedicles, reliably restoring and maintaining spinal stability, and thus offering a novel therapeutic option for clinicians.
