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
objectiveThis study evaluates the efficacy and outcomes of endoscopic third ventriculostomy combined with choroid plexus cauterization (ETV + CPC) as a primary treatment for hydrocephalus associated with Chiari II malformation in infants.
methodsThis retrospective study analyzed 53 infants, all under 12 months of age and post-myelomeningocele repair, who presented with hydrocephalus (Evans' Index > 0.3 or Frontal occipital horn ratio (FOHR) > 0.4). All patients underwent Endoscopic third ventriculostomy (ETV) and bilateral choroid plexus cauterization (CPC) using a rigid endoscope. Success was defined as shunt-free survival with clinical and radiological improvement over a 12-month follow-up period.
resultsThe cohort of 53 infants (28 males, 25 females) had a mean age of 3.4 months, with 36% consanguinity. Patients were stratified into three age groups: < 3 months (n = 13), 3-6 months (n = 19), and 6-12 months (n = 21). The ETV + CPC success rate showed a positive correlation with age: 54% in the youngest group, 63% in the middle group, and 67% in the oldest group. Of the 20 failures, 14 required ventriculoperitoneal shunts (VPS), and 6 were managed with re-endoscopy for stoma closure. Meningitis was the most common complication (15%), with all affected patients eventually requiring a VP shunt.
conclusionETV + CPC offers an effective, safe, and durable alternative to traditional VPS for infants with Chiari II-associated hydrocephalus. It significantly reduces shunt dependency and its associated long-term complications. Success rates improve with advancing age, making it a viable first-line surgical option in pediatric neurosurgery, particularly in resource-limited settings.
