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

A 38-year-old man without skin rash was admitted to our hospital for recurrent cerebral infarctions. Cerebral angiography revealed vertebral artery stump syndrome (VASS), and a high varicella-zoster virus (VZV) antibody index suggested VZV vasculopathy. Treatment with aspirin and anticoagulants was initiated, along with intravenous acyclovir and methylprednisolone sodium succinate. No further cerebral infarction was observed. Clinicians should be aware that VZV vasculopathy may underlie ischemic stroke in young adults and VASS even in the absence of a rash. An early diagnosis and appropriate treatment have contributed to favorable clinical outcomes.
