Aneurysmal Subdural Hematoma: A Systematic Review.
Synthesis in Neurocritical care, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundAneurysmal subdural hematoma (aSDH) is a rare complication of aneurysm rupture, affecting between 0.5 and 7.9% of patients with aneurysmal subarachnoid hemorrhage (aSAH). The clinical presentation, course, and outcomes of these patients are largely unknown.
objectiveThis study aims to systematically review the literature to evaluate the demographics, clinical presentation, aneurysm location, treatment options, and outcomes of patients with aSDH with and without aSAH.
methodsIn accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines, we conducted a systematic review of three databases (PubMed, EMBASE, and Google Scholar). From identified reports, we extracted data on patients' demographics, clinical presentation, imaging findings, surgical interventions, and clinical outcomes. We compared clinical outcomes, need for surgical treatment, and aneurysm location between patients with aSDH with and without concurrent aSAH using χ
resultsWe identified 112 articles with a total of 270 patients (70% women, mean age 52.8 [± 15.5] years). The most common aneurysm locations were the middle cerebral artery, followed by the posterior communicating artery, and the internal carotid artery. Patients with isolated aSDH fully recovered more frequently than those with concomitant aSAH (38% vs. 6%). The presence of aSAH increased the odds of unfavorable outcome (odds ratio [OR] 2.68, 95% confidence interval [CI] 1.34-5.37). Surgical treatment was inversely associated with unfavorable outcome in the univariable (OR 0.48, 95% CI 0.28-0.84) but not in the multivariable analysis (OR 0.76, 95% CI 0.35-1.66).
conclusionaSDH occurs infrequently. Simultaneous presence of both aSDH and aSAH from an aneurysmal source is associated with poor outcomes. Surgical treatment is associated with lower rates of unfavorable outcomes including death and severe disability.
