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
Open-door laminoplasty is an established posterior decompression technique for multilevel cervical myelopathy. However, the procedure is technically demanding and may result in complications such as hinge fracture, facet joint violation, and improper gutter placement. The authors present an operative video demonstrating O-arm-based intraoperative navigation during open-door laminoplasty in a 75-year-old man with multilevel ossification of the posterior longitudinal ligament (OPLL) and severe cervical canal stenosis. Navigation allowed precise localization of the medial facet, controlled hinge preparation, and accurate screw placement. Postoperative CT confirmed adequate decompression without complications, suggesting that navigation may enhance the safety and precision of laminoplasty.
