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

Cardiac amyloidosis is characterized by the deposition of amyloid fibrils, which cause complications such as mitral regurgitation (MR). The efficacy of transcatheter mitral edge-to-edge mitral repair (TEER) in patients with amyloidosis remains uncertain. We herein present four cases of TEER for transthyretin cardiac amyloidosis. TEER reduced the MR in all cases. However, two of the four individuals died within one year, and in one case, a recurrent MR deterioration occurred. Although TEER can reduce MR in individuals with cardiac amyloidosis, the long-term outcomes appear to be poor owing to disease progression or comorbidities, thereby underscoring the need for careful patient selection.
