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
objectiveDandy-Walker syndrome (DWS) is often associated with hydrocephalus, yet the choice between lateral ventriculoperitoneal shunt (VPS) or posterior cranial fossa cystoperitoneal shunt (CPS) is still controversial. This retrospective study aims to compare the clinical features, cranial imaging changes, and clinical outcomes before and after these two different surgical procedures. This research seeks to inform surgical decision-making in treating DWS-related hydrocephalus.
methodsClinical data from 12 children with DWS-related hydrocephalus (1 case of Dandy-Walker malformation, 11 cases of Dandy-Walker variant) treated between January 2010 and June 2024 were retrospectively analyzed. Among these, eight patients underwent VPS, whereas four received CPS. The follow-up outcomes were classified into good, fair, and poor based on established criteria, including the Evans index, Vineland Adaptive Behavior Scales (VABS) scores, and the presence or absence of hydrocephalus or interstitial edema.
resultsThe follow-up duration ranged from 6 months to 13 years, yielding nine cases with good outcomes and three fair outcomes. Among the VPS group, two patients achieved normal postoperative ventricular size, while six exhibited mild to moderate ventricular dilation. Seven patients showed good cerebellar vermis development, and all of these patients achieved good outcomes. In contrast, the CPS cohort includes one case with mild ventricular dilatation and three cases with moderate ventricular dilatation. Three CPS cases showed cerebellar vermis dysplasia, with one case exhibiting persistent cerebellar vermis dysplasia postoperatively. One patient in the CPS group had good outcomes, while three had fair outcomes. The choice of shunt procedure was statistically significantly associated with clinical outcome (χ
conclusionChildren with DWS-related hydrocephalus who undergo hydrocephalus treatment via a single shunt procedure exhibit well-developed cerebral structures and may have better outcomes with VPS than with CPS.
