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
purposeTo assess the feasibility of a new technique for antegrade insertion of LC-II screws, guided solely by the obturator-outlet view.
methodsFrom September 2020 to September 2025, patients with pelvic and/or acetabular fractures involving disruption of the supra-acetabular corridor treated with antegrade insertion of a LC-II screw in our hospital were included in this study. The procedure of LC-II screw insertion was performed solely guided by the obturator-outlet view, referencing with two anatomical points, namely the anterior inferior iliac spine and a virtual anatomical point. Postoperative CT scans were carried out to assess whether the LC-II screws were placed correctly within the bony corridor. Peri- and postoperative complications were documented.
resultsThirty-seven long, large-diameter (≥ 7 mm) LC-II screws were inserted in a total of 20 consecutive patients. The average length of these 37 screws was 115.8 mm. The procedure was performed without any noted wound infections or related vascular, neurological, and visceral complications. Postoperative CT images confirmed that all 37 LC-II screws were correctly placed within the bony corridors, with no instances of screw penetration. All patients were followed up for an average of 19.1 months (range, 6.1- 37 months). No cases of screw loosening, breakage, or bone union failure were observed.
conclusionsThe technique for antegrade insertion of LC-II screws, guided solely by the obturator-outlet view is a feasible surgical procedure. The virtual anatomical point has been shown to be a reliable anatomical landmark in our surgical procedure.
