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
Introduction: In corn pest and disease prevention, traditional blanket pesticide spraying has led to significant pesticide waste and environmental pollution. To address this challenge, research into precision agricultural equipment based on computer vision has become a hotspot. Methods: In this study, an integrated system named the FGA-Corn system is investigated for precision pesticide application, which consists of three important parts. The first part is the Front Camera Rear Funnel (FCRF) mechanical structure for efficient pesticide application. The second part is the Agri Spray Decision System (ASDS) algorithm, which is developed for post-processing the YOLO detection results, driving the funnel motor to enable precise pesticide delivery and facilitate real-time targeted application in specific crop areas. The third part is the GMA-YOLOv8 detection algorithm for center leaf areas. Building on the YOLOv8n framework, a more efficient GHG2S backbone generated by HGNetV2 enhanced with GhostConv and SimAM is proposed for feature extraction. The CM module integrated with Mixed Local Channel Attention is used for multi-scale feature fusion. An Auxiliary Head utilizing deep supervision is employed for improved assistive training. Results and discussion: Experimental results on both the D1 and D2 datasets demonstrate the effectiveness and generalization ability, with mAP@0.5 scores of 94.5% (+1.6%) and 90.1% (+1.8%), respectively. The system achieves a 23.3% reduction in model size and a computational complexity of 6.8 GFLOPs. Field experiments verify the effectiveness of the system, showing a detection accuracy of 91.3 ± 1.9% for center leaves, a pesticide delivery rate of 84.1 ± 3.3%, and a delivery precision of 92.2 ± 2.9%. This research not only achieves an efficient and accurate corn precision spraying program but also offers new insights and technological advances for intelligent agricultural machinery.
