A deep learning algorithm for coronary heart disease prediction based on retinal fundus photographs and optical coherence tomography.
Article in BMC medical imaging, 2026. 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
backgroundCoronary heart disease (CHD) is a major cause of mortality worldwide. This study aimed to develop and validate a multimodal deep learning algorithm using retinal imaging to assist in CHD risk assessment.
methodsIn this retrospective study, we developed a deep learning algorithm that integrates retinal fundus photographs and optical coherence tomography (OCT) images. A clinical nomogram was also developed by combining the imaging-based predictions with clinical risk factors. Model performance was evaluated on internal validation and test cohort using receiver operating characteristic (ROC) analysis and calibration curves.
resultsThe algorithm was developed and validated using a dataset of 505 patients, which included 282 with CHD. On the training cohort, the model achieved an area under the curve (AUC) of 0.9954 (95% CI: 0.9904-1.0000). On the independent validation and test cohorts, the model achieved AUCs of 0.9834 (95% CI: 0.9556-1.0000) and 0.9138 (95% CI: 0.8404-0.9871), respectively. The nomogram demonstrated an AUC of 0.9963 (95% CI, 0.9923-1.0000) on the training cohort, and AUCs of 0.9423 (95% CI, 0.8626-1.0000) and 0.9153 (95% CI, 0.8289-1.0000) on the internal validation and test cohort, respectively.
conclusionsThis study demonstrates the feasibility of using a deep learning algorithm based on retinal imaging for CHD risk stratification. Future prospective, multicenter studies are needed to validate these findings and evaluate their potential clinical utility.
