Spontaneous intracranial hypotension - Neurological symptoms, diagnosis, and outcome.
Article in European journal of neurology, 2025. 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
backgroundSpontaneous intracranial hypotension (SIH) is a rare secondary headache disorder caused by spinal leakage of cerebrospinal fluid. Specialized treatment of SIH consists of epidural blood patches (EBPs), fibrin patching, endovascular sealing, and surgery. The aim of this paper was to characterize SIH patients identified at a tertiary headache center.
methodsEighty patients with SIH identified at the Danish Headache Center were included in this clinical cohort study. Data on demographics, clinical presentation, imaging findings, effect of EBPs, and invasive procedures were collected in a standardized manner. Prognostic elements of EBP treatment outcome were evaluated statistically with success defined as a minimum 30% intensity reduction sustained for at least 1 month.
resultsThe average age was 47 years and 53% were female. Peracute and subacute onset was noted in 35% and 36%, respectively. Orthostatic headache was noted in 85% of cases. The median Bern score was 4, and of identified leaks, 52% were type 1, 22% type 2, 22% type 3, and 4% type 4 (defined as peripheral leakage distally for the root pouch). Successful treatment response was 34% for EBPs and 90% for invasive procedures. Prepontine cistern effacement was more prevalent in patients with successful first EBP than without (p = 0.013).
conclusionSIH patients presented with a wide variety of symptoms with high prevalence of orthostatic headache. Peracute onset was noted in 35% and calls for more awareness in the acute setting. We found prepontine cistern effacement to be a potential predictor of a successful first epidural blood patch.
