1 · What the graph read from 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.

2 · The registry

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 case report describes early rupture of an expanded polytetrafluoroethylene (ePTFE) loop used in mitral valve repair, likely due to leaflet fixation with 5/0 polypropylene suture. A 52-year-old man developed recurrent mitral valve regurgitation 3 weeks postoperatively. Reoperation revealed rupture at the fixation site. This case suggests that ePTFE may be a more suitable material than polypropylene for leaflet fixation to prevent early loop failure.
