Deep Learning-Based Segmentation of Coronary Arteries and Stenosis Detection in X-Ray Coronary Angiography.
Article in JACC. Advances, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundDeep learning applications may assist in automatically detecting coronary arteries on invasive coronary angiography (ICA).
objectivesThe authors aimed to train deep learning models for the segmentation of coronary arteries and the detection of significant stenoses on ICA, conduct external validation, and compare the performance with expert variabilities.
methodsICA studies from Amsterdam University Medical Centers (center 1) and Emory University Hospital (center 2) were retrospectively collected. Contours of the main coronary arteries and their ≥50% stenoses were manually segmented using dedicated software. Deep learning-based models were created using data from center 1, center 2, and both centers. The performance of the models was assessed on unseen data and compared to expert variability.
resultsA total of 10,573 ICA images were used to train models: 9,065 from center 1 (n = 2,624) and 1,508 (n = 456) from center 2. Validation was done on 186 center 1 images and 123 center 2 images. The segmentation model trained on data sets from both centers had the highest median Dice coefficient (0.86; IQR: 0.81-0.88). The stenoses detection algorithm trained on both centers achieved a detection rate of 0.67 (95% CI: 0.63-0.71), similar to expert agreement (0.65; 95% CI: 0.63-0.68). The model trained on the data with the most stenoses yielded the highest stenosis detection rate (0.67; 95% CI: 0.64-0.71). When matched for data set size and proportion of stenoses, the models trained on both centers performed similarly.
conclusionsThe models achieved performance levels on par with experts in coronary artery segmentation and detection of significant stenoses in the main arteries.
