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

Right ventricular outflow tract aneurysms are rare postoperative complications associated with congenital heart diseases. The hemodynamics associated with a right ventricular outflow tract aneurysm serve as important risk indicators for aneurysm expansion and thrombus formation; however, they have not been thoroughly evaluated. A 3-year-old girl was diagnosed with Double-outlet right ventricle who underwent surgical correction with patch enlargement of the right ventricular outflow tract at 2.5 years. Postoperatively, a patch expansion mass was observed and 4D flow MRI showed vortex flow. Notably, vortex flow within the aneurysm persisted even after balloon dilation of the unilateral pulmonary artery. Evaluating blood flow in right ventricular outflow tract aneurysms is crucial for determining prognosis and guiding treatment strategies.
