1 · What the graph read from it

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.

2 · The registry

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

Purpose: Magnetic resonance (MR)-guided radiotherapy offers superior soft-tissue visualization, enabling more precise contouring and reduced toxicity. However, this workflow poses challenges for trainees. This study evaluated whether structured contouring training modules improve contouring accuracy and efficiency for radiation oncology trainees. Methods: Residents contoured the prostate and pelvic organs-at-risk (OARs) from MR images in three phases: baseline, after reviewing a written contouring module, and after receiving personalized feedback with a training video. Automated tools using Boolean logic provided quantitative and visual feedback.Resident contours were compared against gold-standard contours established by staff radiation oncologists. Accuracy was assessed using Dice Similarity Coefficient (DSC), 95th percentile Hausdorff Distance (HD), and Absolute Volume Difference (AVD). Efficiency was measured as contouring time per case. Friedman and Wilcoxon signed-rank tests with Benjamini-Hochberg adjustment were applied, and significance was defined as Results: Four trainees contoured five cases in each phase. When data were combined across structures, HD and AVD improved significantly (8.332 mm to 6.117 mm, Conclusion: Structured MR contouring training improved both accuracy and efficiency. Incorporating this training into residency curricula may better prepare residents for MR-guided radiotherapy and make adaptive radiotherapy workflows more streamlined.
