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
Accurate posture assessment is essential for diagnosing and managing health issues related to postural disorders. Existing mobile applications rely on 2D imaging and analyzing reflective markers placed on anatomical landmarks of the human body without comprehensive view of body's posture. A mobile tool of 3D body reconstruction-based posture assessment is proposed in this paper. A smartphone is used to capture video circling around a static standing person in an approximate A-pose. Some specific multi-view body images using body orientation estimation are extracted from video. Then OpenPose and U2Net are employed to extract 2D joints and contours of each image. Camera poses are estimated using feature matching, and 3D joints are reconstructed from 2D joints and camera parameters. Multi-view projection contour consistency is used to iteratively optimize SMPL parameters for accurate 3D body reconstruction. From reconstructed 3D SMPL body, the required parameters for posture assessment including key 3D body points, joint angles, and spatial measurements, etc. can be easily obtained and calculated. Finally, assessment results are compared with artificial intelligence posture evaluation and correction system (APECS), and reliability is evaluated using Cohen's d and the Intraclass Correlation Coefficient (ICC). The proposed 3D body-based method achieved over 90% accuracy in identifying common postural abnormalities, such as uneven shoulders and forward head posture. The posture assessment results were in close agreement with existing method. 3D body reconstruction is demonstrated to be an effective method for posture assessment. Smartphone video-based posture assessment provides a user-friendly, visualized, abnormal posture screening tool.
