Persistent Hypersomnolence Following Aneurysmal Subarachnoid Hemorrhage: A Case Report.
Article in Cureus, 2026. 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
Persistent excessive daytime sleepiness (EDS) following aneurysmal subarachnoid hemorrhage (SAH) is an underrecognized complication that may impair quality of life and patient safety. We report a 60-year-old man with EDS that had been present for approximately one year and progressively worsened following aneurysmal SAH despite adequately treated obstructive sleep apnea. Overnight polysomnography (PSG) demonstrated well-controlled sleep-disordered breathing, while the multiple sleep latency test (MSLT) revealed severe objective hypersomnolence, supporting a diagnosis of secondary central hypersomnia. Alternative causes of EDS were excluded through clinical evaluation and objective sleep testing. The patient experienced meaningful improvement following treatment with modafinil. This case highlights the importance of considering secondary central hypersomnia in patients with persistent EDS after aneurysmal SAH. It demonstrates the value of PSG followed by MSLT in establishing the diagnosis and guiding management.
