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
purposeTo characterize symptomatic retinal ischemic events following cardiovascular procedures and evaluate their clinical features and association with cerebral ischemia.
methodsWe conducted a retrospective review of OCT-confirmed acute retinal ischemia at a tertiary center (2015–2024), including patients who had undergone a cardiovascular procedure within 30 days preceding symptom onset.
resultsThirteen patients (mean age 67±8.5 years, 84.6% male) developed retinal ischemic events following cardiac catheterization (n=4), valve replacement (n=3), carotid interventions (n=3), and other procedures (n=3). All had cardiovascular risk factors; 85% were on antithrombotic therapy. Branch retinal artery occlusion was most common (69.2%), followed by paracentral acute middle maculopathy (23.1%) and central retinal artery occlusion (7.7%). Symptom onset ranged from immediately post-procedure to 28 days, with varying clinical characteristics across different timeframes. Neuroimaging revealed cerebral ischemia in 7 of 10 patients (70%).
conclusionsRetinal ischemic events following cardiovascular procedures presented across a spectrum of timing, with varying clinical features that may suggest different pathophysiological mechanisms such as procedural embolization, perioperative hypoperfusion, or delayed complications from evolving embolic sources.The high rate of concurrent cerebral ischemia supports prompt brain imaging. These events, regardless of timing, should prompt comprehensive neurological and cardiological evaluation, as they may indicate systemic or evolving cardioembolic disease even in patients on antithrombotic therapy.
