Post-Coital Intracranial Haemorrhage: A Nigerian Regional Experience.
Article in Nigerian medical journal : journal of the Nigeria Medical Association. 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
Background: Post-coital intracranial haemorrhage (PC-ICH) is a non-traumatic intracranial bleeding occurring during or within 30 minutes of sexual intercourse. In sub-Saharan Africa, poorly controlled hypertension, delayed presentation, and limited access to neurosurgical care compound its lethality. No prospective series from the region exists. Methodology: Prospective observational cohort study at a tertiary referral centre in a metropolitan city in the south-south region of Nigeria, from January 2021 to December 2025. Consecutive adults presenting with CT-confirmed, non-traumatic ICH where coitus was the immediately preceding activity were enrolled. The primary outcome was the six-month Glasgow Outcome Scale (GOS) score; secondary outcomes were in-hospital mortality and in-hospital complications. Results: Fifty-two patients were enrolled over five years (mean age 49.6 ± 9.8 years; 57.7% male). Hypertensive ICH was the most common aetiology (53.8%; n=28), followed by aneurysmal subarachnoid haemorrhage (aSAH; 36.5%; n=19) and other/undetermined causes (9.6%; n=5). Median time from ictus to hospital arrival was 41.2 hours; only 11.5% presented within six hours. Overall six-month mortality was 19.2% (n=10); a favourable functional outcome (GOS 4-5, i.e. moderate disability or good recovery) was achieved in 59.6% (n=31). Low GCS on admission (OR 9.4; 95% CI 2.6-34.0; p < 0.001), haematoma expansion or rebleeding and presentation delay >24 hours (OR 4.3; p = 0.012) were the strongest independent predictors of poor outcome. Conclusion: PC-ICH in the region is predominantly a complication of uncontrolled hypertension in middle-aged men. Delayed presentation, driven by sociocultural stigma, misdiagnosis, and financial barriers, is the most actionable determinant of poor outcome. Intensification of hypertension control, structured emergency triage for post-coital thunderclap headache, and removal of financial barriers to neurosurgical care are urgently required.
