Infratentorial Pressure Monitoring in Cerebellar Stroke: Feasibility and Prognostic Utility.
Article in Neurocritical care, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundAlthough supratentorial intracranial pressure (ICP) monitoring represents the current standard in neurocritical care, its validity for assessing infratentorial pathologies remains uncertain. This multicenter, prospective study aimd to (1) evaluate the feasibility and clinical utility of infratentorial ICP monitoring in acute posterior fossa pathologies and (2) develop a prognostic model for functional outcomes based on infratentorial pressure dynamics.
methodsWe conducted a prospective cohort study across three tertiary neurovascular centers in Germany (2021-2024), enrolling 35 consecutive patients with cerebellar stroke requiring surgical decompression and external ventricular drainage. All participants underwent simultaneous supratentorial and infratentorial ICP monitoring for seven posteroperative days. Functional outcomes were assessed using the modified Rankin scale at discharge and at six-month follow-up (FU). The primary end point was the comparison of ICP gradients between compartments; secondary analyses evaluated the association between infratentorial ICP and functional outcomes.
resultsThe mean infratentorial ICP was significantly higher than the supratentorial ICP (11.9 mm Hg [95% confidence interval (CI) 10.5-13.3] vs. 8.8 mm Hg [95% CI 7.4-10.1], P < 0.001). Patients with unfavorable outcomes had significantly higher infratentorial ICP values compared with those with favorable outcomes at FU (13.1 mm Hg [95% CI 11.1-15.1] vs. 9.5 mm Hg [95% CI 6.8-12.1], P = 0.042). Multivariate logistic regression analysis identified a novel scoring system-calculated as patient age (years) plus four times the mean infratentorial ICP (mm Hg)-as a significant predictor of unfavorable outcomes at both discharge and FU (P < 0.001 and P = 0.001, respectively), with area under the curve (AUC) values of 0.88 and 0.89. A cutoff value of 115 was established to predicting unfavorable outcomes at FU.
conclusionsThis study establishes that infratentorial ICP monitoring (1) reveals clinically significant pressure gradients undetctable by supratentorial measurement alone, (2) provides superior prognostic information compared with conventional monitoring, and (3) can be safely implemented with 94% technical success rate. These findings advocate for the integration of infratentorial ICP assessment into the neurocritical care paradigm for posterior fossa pathologies.
