Case Report and Minireview of the Literature on Blunt Azygos Injury.
Article in Juntendo Iji zasshi = Juntendo medical journal, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
Azygos vein injury seems to be an uncommon cause of hemothorax and hemomediastinum; however, this injury is potentially fatal. We report a fatal case of blunt azygos injury and a PubMed search was undertaken to identify English articles from 1989 to 2022 using the key words "azygos", "injury" and "blunt". We found 28 articles about blunt azygos injury and 39 patients including the present case (average 41.2 years [range: 18-81 years]; male, n=20; female, n=19). The other variables were as follows: right hemothorax (n=32); unstable circulation on arrival (n=32); and survival (n=19; unknown, n=2). These cases were divided into two groups based on the outcome: the survival group and the fatal group. There were no significant differences with regard to the year of the report, age, sex, rate of right rib fracture, rate of preoperative computed tomography (CT) examination, rate of associated injury, and rate of operation. The rate of shock on arrival in the survival group was significantly lower than that in the fatal group. The rate of azygos arch injury in the survival group was significantly greater than that in the fatal group. The emergency physician must consider azygos vein injury as a possible cause of right hemothorax when a patient with blunt chest trauma presents persistent hypotension.
