Bilateral Coronary Ostial Atresia: A Malignant Anatomic Variant.
Article in JACC. Case reports, 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
backgroundBilateral coronary ostial atresia (BCAO) is one of the rarest congenital cardiac abnormalities. Consequently, outcomes in patients with bilateral coronary ostial atresia are poorly characterized. CASE SUMMARY: We report the clinical course of a term girl with prenatally diagnosed ventricular septal defect and normal ventricular function, who rapidly deteriorated at 6 weeks. Catheterization confirmed BCOA with the right coronary artery connecting to the right atrium via a fistula and the left coronary filling from the right ventricular outflow tract. DISCUSSION: This case highlights the malignant clinical course of BCOA. Early detection is limited by difficulty detecting coronary anatomy on echocardiography. Outcome was poor despite extracorporeal membrane oxygenation support. To our knowledge, this variant of BCOA has not been described. TAKE-HOME MESSAGES: BCOA is rare and lethal; early stability may mask rapid deterioration. Suspicious coronary imaging warrants urgent angiography. Limited management options include extracorporeal membrane oxygenation or transplantation.
