Spontaneous Bilateral Subdural Hematomas Associated With Resolving Hypertensive Intraparenchymal Hemorrhage: A Case Report.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Intraparenchymal hemorrhage (IPH) and subdural hematoma (SDH) are well-recognized separate clinical entities. We present a case of spontaneous bilateral SDHs identified during the resolution phase of a hypertensive IPH in a 73-year-old male. The patient initially presented unconscious with an acute right-sided thalamoganglionic IPH confirmed via non-contrast brain computed tomography scan. Conservative management led to neurological improvement, but routine follow-up imaging at eight weeks unexpectedly demonstrated bilateral SDHs without clinical deterioration. Further imaging at 14 weeks indicated progressive enlargement of the right-sided SDH. Extensive diagnostic evaluations, including magnetic resonance imaging and magnetic resonance venography, identified no underlying vascular or structural abnormalities, besides ruling out other predisposing factors such as coagulation disorders, preceding trauma, or brain atrophy. We hypothesize that intracranial pressure fluctuations during the resolution of IPH contribute to the formation of spontaneous SDH. This case highlights a potential cause of unexplained SDH in the context of a resolving IPH, underscoring the knowledge gap in pathophysiology and its underlying mechanisms.
