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

Noncommunicating hydrocephalus is a rare complication of aseptic meningitis and is predominantly characterized by the obstruction of cerebrospinal fluid (CSF) absorption. Traditional treatment methods include external ventricular drainage (EVD) and ventriculoperitoneal (VP) shunt. However, endoscopic third ventriculostomy (ETV) might also be effective in the case of aseptic meningitis. A 19-year-old woman presented with fever, lymphadenopathy, and arthritis, followed by headache and vomiting. Magnetic resonance imaging (MRI) showed no hydrocephalus. CSF analysis revealed mild pleocytosis and elevated protein levels, with negative cultures, leading to the diagnosis of aseptic meningitis. After an initial recovery with supportive care, the patient returned a month later with an acute progressive headache and altered consciousness. Computed tomography (CT) revealed lateral and third ventricular enlargement, while MRI showed cerebellar swelling and foraminal adhesions, indicative of obstructive hydrocephalus. ETV was performed through the right anterior horn of the lateral ventricle. Postoperative recovery was uneventful, and the patient remained asymptomatic after steroid treatment. ETV is a viable option for treating noncommunicating hydrocephalus associated with aseptic meningitis, even when CSF malabsorption is present.
