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

objectiveTo develop an experimental porcine model of tricuspid regurgitation using two induction routes: the inferior vena cava and superior vena cava.

methodsTricuspid regurgitation was generated using the loop wire cutting method. The tricuspid regurgitation jet direction was controlled by accessing the valve through the inferior (n = 7) or superior (n = 6) vena cava. The occurrence, direction, and progression of tricuspid regurgitation were assessed postoperatively, and echocardiography was performed at 4 to 6 weeks. Right heart dilatation was assessed using computed tomography after 6 weeks.

resultsModerate to severe or torrential tricuspid regurgitation occurred immediately after the procedure in 12 of 13 animals. The jet was directed toward the septum in five of seven animals in the inferior vena cava group and toward the posterolateral side in four of six animals in the superior vena cava group. The dimensions of the right heart (right atrium, ventricle, and tricuspid valve annulus) were significantly enlarged at the 4- to 6-week follow-up echocardiographic examination and confirmed to be enlarged by computed tomography, independent of the route used.

conclusionThe loop wire cutting method successfully induced a disease model of tricuspid regurgitation while controlling the regurgitation jet direction via two procedural routes.
