Percheron-like artery infarction after transsphenoidal surgery: illustrative case.
Article in Journal of neurosurgery. Case lessons, 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
backgroundThe transsphenoidal approach to the skull base has enjoyed increasing popularity for surgery of the sellar region avoiding brain retraction and causing few severe complications. While vitally important vessels in this region show a high degree of variability, some anatomical variants might be involved in characteristic complications. OBSERVATIONS: We present the case of a 40-year-old female patient with acromegaly due to a pituitary adenoma that was transsphenoidally operated. Postoperatively, the patient presented with bilateral unresponsive mydriasis, loss of consciousness and tetraparesis. An MRI showed well-circumscribed bilateral paramedian thalamic infarctions which indicated a rare Percheron-like artery. At 2-year follow-up examination the patient was dramatically improved but with a profound impact on her ability to interact with the world. LESSONS: The basilar artery or perforators might be injured during dissection of suprasellar lesions. This vascular territory is essential to interaction of the brain with the outside world. We conclude that we will approach future suprasellar adenomas strictly intracapsularly.
