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
purposeSpinal robotic guidance platforms, which rely on computed tomography (CT) or cone beam CT (CBCT)-based navigation, enable precise preoperative planning and intraoperative placement of pedicle screws. However, they also result in significant radiation exposure to both patients and clinical staff. A recently FDA- and CE-approved high-resolution synthetic computed tomography (sCT) technology allows the generation of CT-equivalent images from magnetic resonance imaging (MRI) data, potentially reducing radiation exposure.
aimTo assess the feasibility of using MRI-derived sCT images for pedicle screw planning and robotic navigation, and to compare patient radiation doses between standard CT-based and sCT-based workflows.
methodsTwelve patients scheduled for thoracolumbar pedicle screw fixation underwent 3T MRI with additional T1-weighted 3D dual-echo gradient-echo (GRE) sequences. These GRE datasets were converted into sCT images using BoneMRI
resultssCT images were visually comparable to conventional CT and fully compatible with the robotic navigation platform for both planning and execution. Replacing CT with sCT reduced patient radiation exposure by 98%, with residual dose primarily resulting from intraoperative fluoroscopy used for image fusion and verification.
conclusionMRI-derived sCT offers a radiation-free alternative to conventional CT for spinal robotic guidance, enabling pedicle screw planning and navigation while eliminating CT-associated radiation exposure.
