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
purposeThis study aims to assess the survival outcomes of ventriculo-peritoneal shunt (VPS) and identify risk factors for shunt failure when using the standardized protocol in Vietnamese children.
methodsThis was a multi-center retrospective cohort study at four pediatric centers in Vietnam. All patients less than 16 years old who underwent initial VPS placement between 2021 and 2024 were included. The Kaplan-Meier method was employed for survival analysis. Risk factors were identified using Cox regression models.
resultsA total of 334 individuals were enrolled with a median follow-up (FU) of 21 months. Brain tumors (59.6%), post-meningitis (14.7%), and congenital abnormalities (14.3%) were the most common etiologies of hydrocephalus. Shunt infection rate was 14.1%. Low rate of full compliance with protocol (39.5%) increased shunt infection (p = 0.01). The 1-, 2-, and 3-year overall survival (OS) of VPS was 69%, 64%, and 61%, respectively, with an estimated mean survival time (ST) of 26 months. Post-meningitis hydrocephalus, non-compliance with shunt protocol, and improper technique were independent risk factors for shunt failure with adjusted hazard ratios (95% confidence interval) (aHR [CI]) of 1.82 (1.09-3.03), 1.69 (1.08-2.64), and 5.57 (2.90-10.69), respectively.
conclusionsThe shunt survival outcomes in Vietnamese children remain consistent with those in other populations in similar settings. Post-meningitis hydrocephalus, non-compliance, and improper technique are independently associated with reduced shunt survival. Recommendations include standardizing surgical techniques and ensuring full compliance with shunt protocol to prevent infection and improve shunt outcomes. This study also underscores the feasibility and efficiency of implementing the standardized shunt protocol in resource-limited countries.
