Reliable deep learning for coronary artery disease detection: a patient-level, statistically validated MRI study.

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
backgroundAccurate detection of coronary artery disease (CAD) from cardiac magnetic resonance (CMR) imaging can support earlier diagnosis and streamlined clinical decision-making.
objectiveThis study evaluated the performance and statistical robustness of two deep learning architectures - DenseNet121 and ResNet50 - for automated CAD classification using multiparametric CMR imaging.
methodsImages were preprocessed using a valid pipeline and partitioned strictly at the patient level. Model performance was quantified through average accuracy, area under the receiver operating characteristic (ROC) curve (AUC-ROC), precision recall, while distributional assumptions were assessed using Shapiro-Wilk tests and variance homogeneity was explored with Brown-Forsythe test.
resultsResNet50 demonstrated the strongest performance, achieving an average accuracy of 90.43%, AUC-ROC of 0.862, and area under the precision recall curve (PR-AUC) of 0.891. DenseNet121 showed lower accuracy (81.72%). Statistical analysis revealed non-normal performance distributions and significant variance differences between models.
conclusionsThe findings indicate that ResNet50 offers a reliable and statistically validated solution for CAD detection from CMR imaging. The combined use of realistic preprocessing and comprehensive inferential testing supports the generation of reproducible and clinically meaningful performance estimates.
