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

Bilateral cerebellar infarction due to unilateral occlusion of the posterior inferior cerebellar artery (PICA) is extremely rare, particularly when a bihemispheric PICA variant is present. We report the case of an 81-year-old male with a history of hypertension and diabetes who presented with recurrent vomiting and gait disturbance, eventually progressing to a comatose state. MRI revealed bilateral cerebellar infarctions sparing the brainstem and ventricular enlargement consistent with obstructive hydrocephalus. Magnetic resonance angiography (MRA) demonstrated occlusion of the right PICA, while an earlier MRA had identified a bihemispheric PICA variant originating from the right vertebral artery and supplying both cerebellar hemispheres. Echocardiography did not reveal any embolic source. This case underscores the clinical importance of early recognition of rare vascular anomalies, such as the bihemispheric PICA variant, which is critical for optimal stroke management and the prevention of complications like obstructive hydrocephalus.
