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

Background: Vertebrobasilar dolichoectasia (VBD) is a vasculopathy characterized by the elongation, widening, and tortuosity of a cerebral artery. Rarely, hydrocephalus results when the extended basilar artery impairs communication of the cerebral ventricle and cerebrospinal fluid dynamics. We experienced such a case when a patient underwent endoscopic third ventriculostomy (ETV) for noncommunicating hydrocephalus with VBD. Case Description: A 54-year-old man presented with cognitive dysfunction and was diagnosed with VBD by magnetic resonance imaging (MRI). Seven years later, he exhibited subacute impaired consciousness due to acute noncommunicating hydrocephalus, undergoing external ventricular drainage (EVD) that improved consciousness. After EVD removal, the noncommunicating hydrocephalus did not recur; however, 7 months later, subacute consciousness impairment due to noncommunicating hydrocephalus was again observed. MRI showed a significant dilation of both lateral ventricles and ballooning of the third ventricle while the right posterior cerebral artery shifted slightly posteriorly. The patient underwent ETV and clinical symptoms improved. One year after the treatment, MRI observed a patent ETV fenestration and no deleterious changes in clinical symptoms were observed. Conclusion: ETV can be an effective treatment for the noncommunicating hydrocephalus with VBD when performed with preoperative assessment of vascular anatomy and attention to vascular injury.
