Anatomic variations in the anterior circulation of the circle of Willis in cadaveric human brains.
Article in International journal of clinical and experimental medicine, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers.
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
objectiveThe Cycle of Willis unites the internal carotid and vertebrobasilar system and maintains the stability of blood supply to the brain. This present study aims to analyze the anatomic variations in the anterior part of the Cycle of Willis.
methodsForty five formalin-preserved human brains (90 cerebral hemispheres) with intact dura mater from Chinese adults were dissected under the surgical microscope. The anterior components of the Circle of Willis were observed and measured. Anatomic variations of this segment were observed and photographed. The data collected in this investigation was statistically analyzed.
resultsIn approximately 13.3% (6/45) of all cerebral samples, a caliber difference of ≥ 0.5 mm was noted between the left A1 and the right segments. The A2 segments of left and right hemispheres were derived from the contralateral A1 segment in 6.7% (3/45) of the brain specimens. Simple anterior communicating artery (ACoA) was observed in 37.8% (17/45) whereas complex ACoA was noted in 60% (27/45) of cerebral samples.
conclusionAs it demonstrates the anatomic variations of ACAC, all surgical approaches should be performed after angiographic demonstrations. Understanding of these anatomic variations plays a pivotal role in neurovascular procedures.
