Evaluation of the ETV success score and its predictive value in pediatric occlusive hydrocephalus: implications for patient counseling.

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
introductionEndoscopic Third Ventriculostomy (ETV) is a well-established treatment for pediatric hydrocephalus, particularly in cases of aqueductal stenosis. The ETV Success Score (ETVSS) is a predictive tool widely used to estimate the likelihood of ETV success based on factors like age. Its accuracy, especially in infants under 3 months, is still debated. PATIENTS AND
methodsThis study evaluates the age-dependency of ETV success in 54 pediatric patients compared to ETVSS predictions. Patients were divided into age and pathology groups according to Kulkarni. Success was defined according the ETVSS criteria. Minimum follow-up was 12 months and included MRI to demonstrate a flow void at the floor or the third ventricle.
resultsOur institutional data revealed a higher overall success rate SR (88%) compared to the ETVSS-predicted rate of 73%. Despite small numbers within subgroups, especially in very young children < 1 month, the success rate was higher than predicted by ETVSS. DISCUSSION: Our results show significantly higher actual SR across all age groups compared to ETVSS predictions (p = 0.035) when selected and performed by an experienced physician. The age groups > 1 year had significantly higher SR close to 100% (p < 0.0001 and p = 0.0038, respectively). This suggests that ETV may be underutilized, particularly in infants, where predicted success rates are pessimistic.
conclusionETVSS is a useful tool for counseling of parents, but differences in institution-specific outcomes should not be neglected. Depending on that, physicians might opt in favor of ETV as primary treatment in occlusive hydrocephalus of very young children, counterbalancing risks and sequalae of VP-shunting.
