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
Difficult retrograde crossing of a severely stenotic aortic valve remains a key technical limitation during transcatheter aortic valve interventions. We describe a novel EBU catheter-assisted parallel wire technique for retrograde aortic valve crossing (EUPASS) that enables 3-dimensional coaxial alignment and controlled guidewire advancement across the valve. EUPASS was applied as a bailout (n = 16) or primary (n = 7) strategy in 23 of 164 patients with severe aortic stenosis and complex anatomy, including frequent bicuspid valves (8 in 23, or 34.8%) and horizontal aortic angulation (16 in 23, or 69.6%). Using a single guiding catheter and parallel straight and looped guidewires, valve crossing and left ventricular apical wire positioning were achieved in all cases, typically within 2 minutes, without procedural complications. The technique provided a stable rail for seamless continuation of balloon valvuloplasty or transcatheter aortic valve replacement. EUPASS represents a simple and reproducible technical solution for challenging retrograde aortic valve crossing.
