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

Occlusions and severe stenoses of the innominate artery (brachiocephalic trunk) are rare and present with a wide variety of clinical manifestations, with hemispheric, vertebrobasilar and right upper limb ischemic symptoms. The most common cause is atherosclerosis. Duplex scanning may show right vertebral artery flow reversal, diminished subclavian flow, and several patterns of right carotid flow disturbance, including slow flow, partial flow reversal during the cardiac cycle and even complete reversal of flow in the internal carotid artery, which is a very uncommon finding. Herein, the authors describe the case of a female patient who was a heavy smoker, had severe stenosis of the brachiocephalic trunk, and had episodes of collapse. Besides the subclavian steal and partial flow reversal in the common carotid artery, duplex scanning also showed high-velocity reversed flow in the internal carotid artery during the entire cardiac cycle, a finding that is not reported in the literature at this magnitude.
