1 · What the graph read from it

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.

2 · The registry

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

Objective: To evaluate the feasibility and clinical efficacy of patient-specific 3D-printed guide plates for pedicle screw placement in the upper cervical spine, compared with the conventional free-hand technique. Methods: A retrospective analysis was conducted on 39 patients who underwent upper cervical spine surgery between June 2009 and June 2022. Patients were divided into a guide plate group ( Results: A total of 141 pedicle screws were placed. The guide plate group achieved a significantly higher rate of perfect screw placement (81.8 vs. 62.3%, Conclusion: Patient-specific 3D-printed guide plates significantly improve screw placement accuracy and reduce operative time, blood loss, and radiation exposure in upper cervical spine surgery, while achieving clinical outcomes comparable to the free-hand technique. This method is a safe and effective alternative for upper cervical pedicle screw fixation.
