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
Airway stents play a vital role in managing central airway obstruction (CAO) caused by lung cancer and other pulmonary diseases by providing structural support to collapsed airways and restoring airflow. However, complications such as stent migration often require urgent medical intervention while early monitoring is essential to reduce the risk. Regular monitoring through bronchoscopy requires anesthesia in the hospital, which causes pain and an economic burden on patients. Computed tomography involves risky radiation and lacks the ability to provide continuous, real-time feedback outside of hospital settings. Here we report a fundamental mechanism of wireless tracking based on magnetic field in a wirelessly powered sensory ring integrated on an airway stent. The sensory ring is designed for continuous, real-time monitoring of stent position and orientation. This sensory ring, integrating an on-board magnetic sensor, and a wearable magnetic field generation system, enable accurate localization by detecting the magnetic field generated externally. The sensory ring is powered wirelessly via a charging coil, ensuring long-term operation. Our system achieves tracking accuracy of 0.5 mm and 2.2 degrees, with a temporal resolution of 0.2 Hz. Beyond migration monitoring, the sensor also detects airway deformation, offering the potential to sense pathological changes associated with lung cancer and other pulmonary conditions. By eliminating the need for radiation-based imaging or bronchoscopy, this approach enables safe, long-term surveillance of stent patency and surrounding tissue conditions. The proposed sensing mechanism and platform are also adaptable in other organs, such as the esophagus, for monitoring stent migration and deformation.
