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
BACKGROUND AND
objectiveArtificial intelligence–based automatic contouring is increasingly integrated into radiation oncology workflows, yet structured education for clinical end users remains limited. This study aimed to describe and evaluate the educational impact of a national training webinar focused on AI-based automatic contouring.
methodsA prospective educational study was conducted during a live national training webinar delivered online. The intervention covered fundamental principles of supervised learning and convolutional neural networks, objectives of medical image segmentation, interpretation of segmentation performance metrics, and key aspects of clinical implementation requiring human validation. Educational outcomes were assessed using a five-item multiple-choice questionnaire administered before and after the webinar. Paired pre- and post-training scores were compared using the Wilcoxon signed-rank test.
resultsAmong the 33 healthcare professionals who attended the webinar, 28 participants (85%) completed both the pre- and post-training assessments and were included in the analysis. Participants represented a multidisciplinary radiation oncology workforce, including radiation oncologists, residents or trainees, medical physicists, dosimetrists, and radiation therapists. The median questionnaire score increased from 3.5 (IQR: 2–4) before training to 5.0 (IQR: 4–5) after training, corresponding to a statistically significant improvement (p < 0.0001).
conclusionsThis national training webinar significantly improved short-term conceptual knowledge related to AI-based automatic contouring among radiation oncology professionals. These findings support the need for scalable, clinically oriented educational initiatives to accompany the safe, critical, and informed integration of AI tools into routine radiation therapy practice.
