Prognostic value of the preoperative study of cerebrospinal fluid dynamics in Chiari malformations: a pilot study.
Article in Acta neurochirurgica, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
purposeIn patient with Chiari type I malformations (CM1), indication for surgery can be difficult to establish. Headaches are a common complaint. Factors that predict headache relief have not been clearly identified. Several studies have aimed to examine cerebrospinal fluid (CSF) hydrodynamics in patients with CM1 by using phase-contrast MRI (pcMRI), which is currently the only non-invasive method for assessing craniospinal hydrodynamics and hemodynamics. People with CM1 present alterations in cerebrospinal fluid (CSF) and cerebral blood dynamics. The objective of the present study was to identify hydrodynamic criteria that are predictive of positive clinical outcome (headache relief) after posterior fossa decompression surgery in patient with CM1.
method41 patients who underwent posterior fossa decompression surgery at Amiens-Picardie University Hospital (Amiens, France) between 2016 and 2021 were retrospectively included. We used preoperative pcMRI to analyze CSF dynamics. Stroke volumes of cerebrospinal fluid were quantified at the aqueduct of Sylvius (SV

conclusionSVaqu may have prognostic value for headache relief following surgery for CM1. Further investigation is warranted. This association is likely related to the recruitment of intraventricular pulsatility, which may help regulate potential intracranial pressure changes. Notably, this pulsatility does not appear to be linked to morphological features.
