Patient-Prosthesis Mismatch After Mitral Valve Replacement Using Bileaflet Preservation Technique for Mitral Regurgitation.
Article in Annals of thoracic surgery short reports, 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
Patient-prosthesis mismatch (PPM) in the mitral valve position is underreported but may occur when both anterior and posterior leaflets are preserved during mitral valve replacement (MVR), a technique that can reduce the area to place an appropriate-size valve. Therefore, balancing the risks and benefits of leaflet preservation is critical, given that certain degrees of left ventricular dysfunction or valvular disease causes may favor bileaflet or partial-leaflet preservation while minimizing the risk for PPM. We report a case of PPM 1 year after MVR with bileaflet preservation in a patient with normal left ventricular size and function who required redo MVR with a larger valve for symptom resolution.
