1 · What the graph read from it

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.

2 · The registry

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

A 70-year-old man with significant aortic regurgitation and a suspected ventricular septal defect presented with exertional dyspnea. Multimodality imaging showed a rare fistulous connection between the right ventricle and the sinus of Valsalva without aneurysmal formation. Surgical aortic valve replacement and patch closure of the fistula were successfully performed. Intraoperative and pathological findings showed no evidence of inflammation. This case highlights the utility of advanced imaging in diagnosing a rare case of sinus of Valsalva-right ventricle fistula and guiding appropriate surgical management. Learning objective: Comprehensive multimodality imaging, particularly transesophageal echocardiography and cardiac computed tomography, enables precise diagnosis and optimal surgical planning for periaortic fistula and aortic regurgitation.
