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
Background: Minimally invasive surgery has gained widespread popularity in clinical practice. Among spinal surgeries, percutaneous pedicle screw placement (PPS) is one of the most widely performed procedures. However, it necessitates high-frequency fluoroscopic guidance to ensure accuracy, resulting in substantial radiation exposure. Therefore, it is crucial to develop a technique that is fast, safe, and minimizes radiation exposure. Objective: We aimed to describe a novel three-step fluoroscopy-guided technique for PPS and preliminarily evaluate the technical feasibility, procedural efficiency, and short-term safety. Methods: This study prospectively enrolled consecutive patients who underwent PPS using either the three-step fluoroscopy-guided technique or the conventional method from December 2024 to February 2025, while data analysis was performed retrospectively. Data collected included operative time, fluoroscopy frequency, screw placement accuracy, and postoperative complications. Results: The three-step fluoroscopy-guided technique required an average of 4 ± 1.12 fluoroscopic exposures per screw, with an average screw placement time of 5.05 ± 0.923 min. In contrast, the conventional method required an average of 18.33 ± 2.89 fluoroscopic exposures per screw and an average placement time of 15.84 ± 4.11 min. And no significant complications, such as neural or vascular injuries, were reported. Conclusion: This pilot study suggests that the three-step fluoroscopy-guided PPS technique is technically feasible and may reduce fluoroscopy usage while maintaining short-term procedural safety, making it a feasible and efficient alternative that warrants further validation in larger cohorts.
