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

backgroundAs an alternative to quadrangular resection (QR), little is known of the potential of chordal replacement (CR) for treating posterior mitral leaflet (PML) prolapse when comparing these two techniques. This study aimed to assess mid- to long-term outcomes of CR versus QR for isolated degenerative PML (idPML) repair.

methodsWe reviewed 112 consecutive patients using CR or QR for idPML repair from 4/2010 to 12/2015. Outcomes were compared before and after propensity score matching.

resultsCR was more used through the minimally invasive approach (CR 59.4%

conclusionsCR is more often used with the minimally invasive approach with less complications and shorter hospital stay. Nonetheless, CR is associated with recurrent MR development over time. Retaining of MV competence after CR demands attention and further investigation.
