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
The amount of rod contour is a critical factor that influences sagittal and coronal alignment for posterior spinal fusion. Distraction techniques to correct spinal deformity, which are often three-dimensional (3D) in nature, are known to cause rod deformation from the ideal, planned rod curvature. Therefore, surgeons often overbend rods to account for this phenomenon. Currently, there is no agreed-upon method to scientifically quantify rod unbending, and no methods offer a 3D analysis. The proposed methodology addresses this gap. By aligning the 3D rod centerlines, the segmented area enclosed between the two lines serves as a measure of rod deformation. This paper presents the foundational principles and concepts for quantifying 3D rod deformation. With further research and clinical implementation, this methodology has the potential to provide valuable surgical insight, which could improve postoperative spinal alignment and outcomes.
