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
backgroundPedicle screws are pivotal in spinal fixation procedures, providing stability and facilitating the correction of spinal deformities. Several designs, including standard, cannulated, fenestrated, and expandable screws, have been developed to optimize fixation strength and address varying patient needs. Standard screws provide reliable fixation, while cannulated screws allow for minimally invasive insertion using a guidewire.
methodsDespite their advantages, complications such as screw loosening, misplacement, and breakage remain prevalent. Loosening is often caused by poor bone quality, suboptimal insertion techniques, or excessive mechanical loading. Misplacement can lead to serious neurological and vascular injuries, necessitating precise preoperative planning and intraoperative imaging. Screw breakage, typically due to fatigue failure, underscores the importance of advanced material selection and biomechanical design. Recent technological innovations, such as 3D-printed patient-specific screws, bioactive coatings, and real-time navigation systems, aim to mitigate these complications. Furthermore, artificial intelligence (AI) is emerging as a powerful tool in enhancing surgical precision and predicting screw behavior, improving preoperative planning, and reducing human error during surgery.
conclusionThis review examines pedicle screw designs, their biomechanical properties, and the associated complications. It also discusses recent advancements in screw technology and AI-driven tools aimed at improving fixation strength, minimizing complications, and optimizing patient outcomes in spinal fusion procedures.
