Incidence But Not Severity of Intracerebral Hemorrhage Shows a Strong Pattern of Seasonal Variation.
Article in Journal of the American Heart Association, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundA strong risk factor for intracerebral hemorrhage (ICH) is elevated arterial blood pressure, which is known to vary by season, with highest values in winter months. The objective was to assess seasonal trends of ICH incidence, clinical severity, and case fatality according to demographic and clinical characteristics.
methodsThis study was conducted on adult patients hospitalized for ICH between 2003 and 2022. Cases were identified from a stroke inpatient quality assurance registry covering the entire Federal State of Hesse, Germany. Population data were derived from the Hessian Bureau of Statistics. Incidence rates (IRs) per 100 000 person-years of ICH, recorded with 4-digit
resultsA total of 33 444 patients were included (mean age, 72.4±13.6 years, 52% men). ICH IR correlated with the season of occurrence, demonstrating a peak in winter (IR winter, 34.6 [95% CI, 33.9-35.4], IR summer, 29.4 [95% CI, 28.7-30.1];
conclusionsThis large cohort study demonstrates a seasonal incidence peak of ICH in winter. Whether ICH can be prevented by better control of arterial blood pressure in seasons with expected incidence peaks will require further studies.
