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

N-type right-sided aortic arch is a subtype of the Adachi-Williams-Nakagawa`s classification for variations in branching patterns of the aortic arch. Kommerell's diverticulum is a rare anomaly and characterized by the aneurysmal dilatation of the proximal portion of an anomalous subclavian artery or of the aorta at the origin of such subclavian artery. Kommerell's diverticulum occurs in association with a right-sided aortic arch with aberrant left subclavian artery. In the present study, we report a cadaver case of N-type right-sided aortic arch accompanied by Kommerell's diverticulum in retroesophageal origin of the left subclavian artery. Interestingly, in this case, the double left brachiocephalic vein was identified around the ascending aorta. To our knowledge, there have been no reported cases of the coexistence of right-sided aortic arch, Kommerell's diverticulum, and double left brachiocephalic vein. The right-sided aortic arch is often associated with congenital heart diseases and other cardiovascular abnormalities. Therefore, the present right-sided aortic arch with Kommerell's diverticulum and double left brachiocephalic vein may give us an important knowledge for cardiovascular anomalies in men from both clinical and embryological aspects.
