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

Abdominal cerebrospinal fluid (CSF) pseudocysts are rare complications of shunt surgery, predominantly reported in pediatric patients undergoing a ventriculoperitoneal (VP) shunt. In contrast, their occurrence following lumboperitoneal (LP) shunt is exceptionally uncommon. We report the case of a 76-year-old woman who presented with recurrent symptoms, including gait disturbance and cognitive decline, approximately three years after undergoing LP shunt placement for idiopathic normal pressure hydrocephalus. Diagnostic imaging, including shuntography and abdominal computed tomography (CT), revealed an abdominal CSF pseudocyst, likely due to peritoneal adhesions from prior abdominal surgery. Reoperation with catheter repositioning successfully relieved her symptoms. This case highlights the necessity of considering abdominal CSF pseudocysts as a differential diagnosis for shunt malfunction, particularly in patients with a history of abdominal surgery. Early diagnostic procedures, such as shuntography and abdominal CT, are critical for timely intervention and symptom resolution.
