Prophylactic Antiseizure Medication in Patients with Lobar Intracerebral Hemorrhage.
Observational study 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
backgroundEarly seizures are a common complication after acute intracerebral hemorrhage (ICH). We tested the hypothesis of whether prophylactic antiseizure medication is associated with lower incidence of early seizures in patients with elevated risk of ICH.
methodsThis study involved a retrospective analysis of a prospective observational cohort, including five academic medical centers with a focus on patients presenting spontaneous ICH on hospital admission in the years 2006 through 2023. We assessed the characteristics of acute ICH and the administration of antiseizure medication. In this observational cohort, the administration of antiseizure medication was at the discretion of the treating physician. We focused on the 300 patients with lobar hematoma location. Age, hematoma volume, and sex were included as covariates in an adjusted regression model to evaluate seizure occurrence. We prospectively recorded the use of antiseizure medications and identified the occurrence of early seizures. Additionally, we conducted an exploratory analysis defining patients who were at risk as those with lobar hematomas, age < 65 years, and hematoma volume ≥ 10 mL. Functional outcomes were assessed using modified Rankin Scale scores three months after event.
resultsThe median age was 72.0 (interquartile range 62.0-80.0) years, and 158 (53%) were female. An early seizure occurred in 43 (14.3%). In patients who did not receive antiseizure prophylaxis, 34 of 157 (21.6%) had an early seizure, whereas in patients who did receive antiseizure prophylaxis, 9 of 143 (6.3%) had an early seizure. Prophylactic antiseizure medication was associated with a reduced incidence of early seizures (adjusted odds ratio 0.25, 95% confidence interval 0.11-0.54, P = 0.0005) in patients at high risk for early seizures. There was no association between prophylactic medication use and modified Rankin Scale scores at three-month follow-up.
conclusionsIn a retrospective analysis of a multicenter cohort of patients at elevated seizure risk after ICH, prophylactic antiseizure medication was associated with a reduced likelihood of an early seizure.
