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

The cerebral arterial circle morphologic variability has been extensively studied. The posterior cerebral artery (PCA) variants are rarely identified, except from the first segment (P1) hypoplasia or absence. Due to its unique morphology, the computed tomography angiography (CTA) of a 34-year-old female patient was further investigated. On the right side, the typical PCA originated as the terminal branch of the basilar artery. An accessory PCA was also identified originating from the right internal carotid artery (ICA), while the right posterior communicating artery was absent. This variant corresponds to the "complete" duplication of the PCA. The left-sided PCA originated from the ICA, while the P1 was hypoplastic, representing the "partial fetal-type PCA." The rest of the cerebral arterial circle was typical. The present case of PCA "complete" duplication corresponds to a scarce variant, with a reported prevalence of 0.04%, while the fetal-type PCA is the most commonly observed variant.
