Recurrent Acute Kidney Injury Due to Atheroembolic Renal Disease: Diagnostic Utility of Fundoscopy.
Article in Cureus, 2025. 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
Atheroembolic renal disease (AERD) is a rare and often underdiagnosed cause of acute kidney injury (AKI), particularly in patients with atherosclerotic disease. We present the case of a 66-year-old man with hypertension, hyperlipidemia, and stage 3 chronic kidney disease (CKD) (baseline creatinine 100-120 μmol/L) who developed AKI after coronary artery bypass graft (CABG) for non-ST-elevation myocardial infarction (NSTEMI), followed by recurrent episodes and progressive renal decline despite no further invasive procedures. Fundoscopic examination revealed Hollenhorst plaques, leading to a clinical diagnosis of AERD. This case underscores the diagnostic value of noninvasive ophthalmologic evaluation in patients at high risk for cholesterol embolism. The patient was managed with supportive measures, including hydration and blood pressure control, which helped stabilize renal function (creatinine improved from 591 to 410 μmol/L). Our objective is to highlight the diagnostic utility of fundoscopy in evaluating unexplained renal deterioration and systemic ischemic symptoms in frail patients where biopsy is contraindicated.
