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
Background: In the past decade, the Ross procedure has reemerged as a promising approach for young adult patients with aortic valve disease. We evaluated its efficacy in restoration of selected aortic hemodynamic parameters in patients with unicuspid aortic valve (UAV) using 4-dimensional (4D) flow magnetic resonance imaging (MRI). This study examined whether the Ross procedure would normalize ascending aorta (AAo) hemodynamics in patients with UAV. Methods: Thirteen patients with UAV disease who underwent the Ross procedure and received preoperative and postoperative 4D flow MRI were matched to healthy controls (n = 52). Systolic peak velocity (PV), wall shear stress, and viscous energy loss (EL) of each MRI were assessed and compared. Results: There was a significant decrease in systolic PV in the AAo postoperatively ( Conclusions: This study demonstrates the value of using 4D flow MRI to understand aortic hemodynamics after the Ross procedure. Additionally, this study shows that in patients with UAV disease, the Ross procedure can normalize aortic hemodynamics similar to healthy controls.
