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 artery of Percheron (AOP) is a rare anatomical variant of the paramedian thalamic vessels in 7-10% of the general population. An AOP infarct can present with rare clinical manifestations like transient loss of consciousness (LOC) and lethargy, as was seen in the patient whose case is discussed in this report, due to the plethora of regulatory inputs and outputs by the thalamus, which cannot be compensated for because of the absence of anastomotic connections. The AOP supplies the reticular activating system (RAS), which regulates consciousness. Ischemia to this area from an AOP infarct can result in the transient LOC, which our patient experienced. The AOP is a small vessel that is often missed on a CT angiogram (CTA) alone due to low resolution. As a result, it is imperative that clinicians utilize MRI to diagnose AOP infarcts in patients who present with symptoms that raise concerns for decreased bilateral thalamic function and transient LOC.
