THE ASSOCIATION BETWEEN ATRIAL FIBRILLATION AND CENTRAL RETINAL ARTERY OCCLUSION: A META-ANALYSIS AND SYSTEMATIC REVIEW
Bibliographic record
Abstract
Introduction
 Central retinal artery occlusion (CRAO) is a condition where the central retinal artery is blocked. Atrial Fibrillation (AF) is commonly associated with retinal embolism that originates anywhere between the heart and the ophthalmic artery. This study aims to explore the incidence of AF in CRAO.
 Methods
 A systematic search was performed in three databases: Pubmed, EBSCO host, and Proquest. Newcastle-Ottawa Scale was used to assess the risk of bias in the study included.
 Results
 Our systematic review comprises six studies, 4 studies included CRAO patients as the study population and AF as the endpoint, and the other 2 studies with CRAO as the endpoint. Meta-analysis of the first group resulted in a significantly favorable AF incident after CRAO with an odds ratio (OR) of 1.46 (95% CI 1.17-1.81, p=0.0007). The second metaanalysis supports CRAO with an OR of 4.86 (95% CI 2.30-10.28, p<0.0001).
 Discussion
 Our study indicates that AF is a significant risk factor for CRAO. Extended cardiac monitoring may play a crucial diagnostic role in CRAO patients, and longer-term monitoring (23 years) may be a reasonable option as part of the diagnostic workup. Short-term monitoring alone may fail to detect a significant proportion of patients with underlying AF.
 Conclusions
 It is crucial to identify AF in preventing ocular infarction. This study revealed that AF was identified as a risk factor in patients with CRAO and vice versa.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
