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
In table tennis training, pose-based motion analysis is of great significance for technical evaluation and training feedback. With the development of Artificial Intelligence (AI), pose estimation provides a new technical approach for real-time and refined motion analysis. This study proposes a Lightweight Attention-enhanced Fusion Pose Estimation Network (LAFPose), which is improved based on YOLOv8m-Pose. The model adopts MobileNetV3 as the backbone feature extraction network, introduces the Convolutional Block Attention Module (CBAM) and the adaptive key point enhancement module, and replaces the up-sampling module with the Content-Aware ReAssembly of Features (CARAFE) module. These designs make the network structure more lightweight and enhance its feature expression capability. Experiments on table tennis videos from the University of Central Florida 101 (UCF101) dataset show that LAFPose achieves an accuracy of 86.8% with a model size of only 33.2 MB and a computational cost of 46 GFLOPS, achieving a better balance between lightweight performance and precision. In the empirical study, 120 athletes receive AI system intervention. Three groups are designed: the real AI intervention group, the false feedback control group, and the traditional training group. The results show that the total motivation score of the real AI intervention group increases from 18.45 to 20.75, and its satisfaction score rises from 3.62 to 4.21. Both scores are significantly higher than those of the other groups (p < 0.001). Cohen's d reaches a large effect size. The results show that the pose-driven motion analysis and real-time feedback mechanism supported by LAFPose exhibit excellent performance in computational efficiency and analysis accuracy, and significantly enhance athletes' participation motivation and training experience. It holds important practical value for the design of intelligent sports training systems and sports psychology research.
