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

purposeThe aim of this study was to investigate the correspondence between the coronary arterial anatomy and the supplied myocardium based on the proposed American Heart Association (AHA) 17-segment model.

methodsSix human cadaveric hearts without signs of infarct were selectively injected with colored contrasted gelatin in the three major coronary arteries. After injection, the hearts were scanned by computed tomography (64-detector scanner LightSpeed VCT, GE Healthcare) with a collimation of 64 × 0.625 mm. Reconstructed image data were analyzed in order to evaluate the blood supply of each myocardial segment.

resultsCoronary artery territory varies due to anatomy variations. Left anterior descending coronary artery (LAD) was the main vessel responsible for the myocardium blood supply in 11 segments. LAD contributed to the blood supply of all apical segments. Left circumflex (LCx) was the main coronary artery for the infero-anterior wall. Right coronary artery (RCA) contributed in all hearts for the blood supply of infero-septal segments. There was an important overlap between LAD and RCA territories at the infero-septal region and between LAD and LCx territories at the antero-lateral region.

conclusionsIn our experiment, LAD territory was larger than the AHA-proposed 17-segment model. The most specific segments were located at the anterior wall and supplied exclusively by LAD. No specific segment could be exclusively attributed to RCA or to LCx. Sometimes, LCx can be the most important artery for the blood supply of the inferior wall even if the origin of the posterior descending artery is the RCA.
