Automatic transesophageal echocardiographic evaluation of patients with mitral valve prolapse: comparison with patients without structural cardiac chamber remodeling (an exploratory study).
Article in Journal of thoracic disease, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: There is a paucity of information concerning automatic mitral valve apparatus (MVA) analysis of patients with mitral valve prolapse (MVP). We aimed to study with an automatic three-dimensional (3D) transesophageal echocardiography (TEE)-dedicated software, patients with moderate and severe mitral regurgitation when compared to patients with no structural cardiac chamber alterations [patients with patent foramen ovale (PFO) who underwent TEE]. Methods: We employed TEE software dedicated to automatic analysis of 34 parameters of the MVA, comparing MVP patients with moderate and severe mitral regurgitation and patients with PFO without cardiac chamber structural alterations. Mitral valve effective regurgitant orifice (ERO) and regurgitant volume were correlated to automatic MVP parameters. Results: Fifty-nine MVP patients and 43 PFO patients were analyzed. All MVP patients presented P2 MVP, 15 (25.4%) with both posterior and anterior prolapse. Twenty-seven automatic parameters (79%) were different concerning MVP and PFO patients (P<0.05): diameters, area, perimeter, height, angle, coaptation width, length, closure line length, and annulus. ERO was 0.43±0.11 cm Conclusions: Automatic mitral valve parameters differed significantly between patients with MVP and those without structural cardiac chamber remodeling. In exploratory analysis, patients in the upper range of ERO values (≥75
