Effect of Operator Experience on Transcatheter Mitral Valve Repair Outcomes.
Review in US cardiology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
Transcatheter mitral valve repair with MitraClip is a novel, intricate therapy for mitral regurgitation that improves survival and quality of life. Similar to other medical procedures, there is a relationship between procedural experience and clinical outcomes. MitraClip results and the efficiency and safety of the procedure all improved with increasing experience at both the institutional and operator level in two large studies from the Society of Thoracic Surgeons and American College of Cardiology Transcatheter Valve Therapy Registry. Patient selection was also found to have a significant role in procedure success. The old adage of "See one, do one, teach one" does not necessarily apply to complex interventions, such as MitraClip, given that the learning curve does not appear to plateau even as operators approach a 150-case experience.
