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 evaluate the clinical value of a two-dimensional(2D) computer navigation system in percutaneous pedicle screw fixation for thoracic spine fractures.
methodsA retrospective study was conducted on 74 patients with acute thoracic fractures who underwent pedicle screw fixation at Fujian Provincial Hospital from January 2019 to January 2022. Patients were divided into a navigation group (n = 34) using 2D navigation-assisted percutaneous screw placement, and a conventional group (n = 40) undergoing freehand screw placement. Screw placement accuracy (Rampersaud grading), intraoperative fluoroscopy times, operative time, blood loss, postoperative pain (VAS scores), and complications were compared.
resultsThe navigation group showed a significantly higher screw accuracy rate (Grades A-B: 94.1% vs. 79.2%, P < 0.001). Fluoroscopy frequency (8.0 ± 1.1 vs. 16.0 ± 2.0, P < 0.001), operative time (90.1 ± 15.5 min vs. 98.1 ± 14.2 min, P < 0.05), and blood loss (50.4 ± 11.1 mL vs. 110.3 ± 17.8 mL, P < 0.001) were all significantly lower in the navigation group. Postoperative VAS scores were significantly lower at 1 week and 1 month (P < 0.001), with no difference at 3 months. Complications included 9 cases of transient neurological symptoms and 2 cases of screw loosening, all without lasting sequelae.
conclusion2D computer navigation-assisted percutaneous pedicle screw fixation improves screw placement accuracy, reduces radiation exposure, and facilitates early postoperative pain relief. These findings support its potential as a practical tool for managing thoracic spine fractures.
