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
Repeated ventriculoperitoneal (VP) shunt failures in children with hydrocephalus often result from abdominal complications or low-pressure hydrocephalus, posing challenges to long-term cerebrospinal fluid (CSF) diversion. Ventriculoatrial (VA) shunting has re-emerged as a viable alternative, supported by modern imaging and venous cannulation techniques. This study evaluated outcomes and revision patterns following VP-to-VA shunt conversion in pediatric patients, focusing on timing and indications for transition. A retrospective cohort study included 52 children (mean age 7.1 years) who underwent conversion between 2012 and 2021 due to abdominal complications or low-pressure hydrocephalus. Primary outcome was shunt survival; secondary outcomes included revision rates, complications, and VP failure trends. After conversion, VA shunts demonstrated longer survival than the preceding VP shunt periods in the same patients, with one-year survival rates of 95.4% versus 68.0% (p = 0.0004). Revision frequency was significantly lower after conversion (0.79 ± 1.25 vs. 4.60 ± 4.79 per patient, p < 0.001). In patients with ≥ 3 VP revisions, inter-revision intervals shortened progressively (295 → 123 days; p = 0.0002), indicating accelerated VP failure. Conversion indications were abdominal complications (69.2%) and low-pressure hydrocephalus (30.8%). The main VA revision causes were lengthening (n = 8), proximal obstruction (n = 4), and thrombosis (n = 4); infection occurred in 6.4% of cases, with no cardiac perforation or shunt nephritis. Our findings suggest VA shunting may serve as a viable and durable salvage option for recurrent VP shunt failure. The third VP failure may represent a practical decision point for considering alternative distal sites, particularly ventriculoatrial shunting. These findings do not advocate VA shunts as first-line therapy but support earlier consideration in selected patients with a failing peritoneal environment.
