Catheter erosion through the rectum 8 years after uncomplicated ventriculoperitoneal shunt placement: illustrative case.
Article in Journal of neurosurgery. Case lessons, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
backgroundDistal bowel perforation by peritoneal catheter (BPPC) is a rare complication following ventriculoperitoneal shunt (VPS) placement for the treatment of hydrocephalus. In some cases, BPPC may present with extrusion through the anus and can occur years after VPS placement. OBSERVATIONS: The authors report the case of a 30-year-old woman who had a VPS placed 8 years prior and found a catheter protruding from her rectum. Having pulled out 1 foot of catheter, she presented to the hospital where the shunt was externalized before concurrent VPS removal and laparotomy to repair the bowel perforation. LESSONS: BPPC with anal extrusion is a rare complication of VPS that can occur years after shunt placement and can present with a broad array of symptoms. BPPC should remain on the differential for people with VPS and systemic symptoms for the duration of their lives. https://thejns.org/doi/10.3171/CASE25365.
