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

backgroundMechanical hemolytic anemia and acute renal failure are rare complications of mitral valve repair. CASE PRESENTATION: We report a unique case of severe hemolytic anemia and severe acute renal failure after mitral valve repair using artificial chordae tendinae. Conservative therapy including plasmapheresis and blood transfusion was not effective. The major cause of the mechanical hemolysis was mild mitral regurgitation originating from the centre of the valve and striking the annuloplasty ring. The hemolytic anemia resolved gradually after the replacement of mitral valve. The new artificial chordae tendinae was found to be completely non-endothelialized in the surgery. Non-endothelialization of artificial chordae tendinae may also play a role in the genesis of mechanical anemia.

conclusionsThe major cause of the mechanical hemolysis was mild mitral regurgitation originating from the centre of the valve and striking the annuloplasty ring. Non-endothelialization of foreign materials might be another mechanism of hemolysis after mitral repair.
