Ommaya reservoir converted to permanent cerebrospinal fluid shunt in neonatal posthemorrhagic hydrocephalus: a risk factors analysis.

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
Objective: To identify factors influencing the transition to a permanent ventriculoperitoneal (VP) shunt in neonates with severe intraventricular hemorrhage (IVH) initially managed with an Ommaya reservoir. Methods: This retrospective study involved 26 neonates diagnosed with IVH in Hebei Children's Hospital from January 2020 to January 2025. These patients were diagnosed with Papile grade III or IV IVH and treated with an Ommaya reservoir. They were categorized into two groups: a permanent shunt group ( Results: Of all study subjects, 10 patients (38.5%) received a permanent VP shunt placement. The 5-minute Apgar score was significantly higher in the permanent shunt group (9.40 ± 1.08) compared to that of the control group (7.25 ± 2.50, Conclusion: In this retrospective study, a higher 5-minute Apgar score (>8.5) was identified as an independent predictor for the requirement of a permanent VP shunt after Ommaya reservoir placement in neonates with severe IVH. This seemingly counterintuitive result may be explained by the impact of a more robust neonatal circulation on the initial hemorrhage volume. Although elevated CSF protein was associated with shunt dependency, it was not an independent predictor. These findings underscore the intricate pathophysiological mechanisms of posthemorrhagic hydrocephalus.
