Impact of heart motion on radiation dose in the heart and left ventricular myocardium during breast cancer treatment.
Article in Frontiers in oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objective: This study aimed to investigate changes in the geometric position and dosimetry differences of the heart and the left anterior descending coronary artery (LAD) during radiotherapy with deep inspiration breath hold (DIBH) in patients with left-sided breast cancer after radical mastectomy. Methods: A retrospective analysis was undertaken on 10 patients with left-sided breast cancer who received DIBH radiotherapy. Changes in the motion position of the heart and the LAD and dosimetric differences were compared by analyzing the planning CT and cone beam CT (CBCT) images. Results: Heart volume was negatively correlated with the heart Conclusions: During the implementation of DIBH radiotherapy for the treatment of left-sided breast cancer, dose assessment for the heart and the LAD provided by static CT planning may contain some inaccuracies. Accordingly, it is recommended to reasonably adjust the organ-at-risk external boundaries in the treatment plan to effectively control the doses received by the heart and the LAD, thereby ensuring patient safety.
