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
backgroundTranscatheter aortic valve implantation (TAVI) is a viable alternative therapeutic approach for patients with severe aortic stenosis (AS), following technological innovations in transcatheter aortic valve systems and advances in clinical expertise, which aim to optimize valve hemodynamics. In this study, we aimed to compare early hemodynamic changes in different types of TAVI valves via two-dimensional echocardiography.
methodsThis retrospective observational study examined patients with severe AS who underwent transfemoral TAVI. Patients were classified according to expansion mechanism (self-expanding valves (SEVs) or balloon-expandable valves (BEVs)) and leaflet position relative to the annulus (supra-annular valves (SAVs) or intra-annular valves (IAVs)). The implanted prostheses were Edwards SAPIEN XT valves (ESV, Edwards Lifesciences, Irvine, CA, USA), Medtronic valves (Core Valve-MCV and Evolut R, Medtronic, Minneapolis, MN, USA), Portico valves (St. Jude Medical, Saint Paul, MN, USA), and Myval valves (Meril Life Sciences, Vapi, India). Baseline two-dimensional transthoracic echocardiography (TTE) datasets were compared with post-TAVI measures obtained before discharge.
resultsIn total (
conclusionsWe found that post-TAVI transaortic gradients of SEVs and BEVs were comparable; however, SAVs were associated with lower transaortic gradients than those of the IAVs. In addition, the frequency of ≥moderate PVL was comparable between the valve groups.
