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
This report discusses a rare case of delayed migration of a Sapien 3 Ultra Resilia (S3UR) valve following transcatheter aortic valve implantation. An 81-year-old Japanese woman had a borderline aortic annular size of 20-23 mm according to the manufacturer's size chart. We chose to implant a smaller S3UR of 20 mm with an 80/20 depth ratio to allow for a second intervention, ensuring good hemodynamics and minimizing paravalvular leak. The patient initially had a favorable outcome despite an accidental 50/50 depth ratio during implantation. On postoperative day 3, the S3UR migrated into the left ventricular outflow tract. Emergency surgical aortic valve replacement was performed to retrieve the migrated valve. Use of the S3UR has led to a growing preference for smaller valve sizes. However, the risk of migration should be recognized. When an accidental 50/50 depth ratio implantation is encountered, post-dilation or second valve implantation should be performed immediately.
