Stroke in Sierra Leone: Insights From a Retrospective Review to Support the Development of a Neurosurgical Department in the Country.
Article in Neurosurgery practice, 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
BACKGROUND AND
objectivesStroke has the largest proportion of the global burden of neurological disorders with projected mortality rates to increase more rapidly in low- and middle-income countries than in high-income countries, and people of African descent are at greater risk. To better understand the burden, risk factors, and care pathways, this study aimed to review the risk factors, clinical presentation, and outcomes of patients presenting with stroke or stroke-like symptoms in a tertiary hospital in Sierra Leone.
methodsA retrospective chart review was conducted of all patients presenting with neurological or neurosurgical conditions from January 2019 through December 2023 and those with stroke or stroke-like symptoms were included in this study.
resultsOne thousand two hundred ninety-seven patients were diagnosed with stroke. Of these, a small majority were male (712, 54.9%), and the mean age was 57.8 years. About a third (38.1%) of the stroke patients were aged 60 years and above, and 562 (43.3%) were between 41 and 60 years. A majority of stroke patients (68.6%) had a prior diagnosis of hypertension, while significantly fewer had a documented diagnosis of diabetes (8.8%) and 4.6% of patients had a known prior stroke. Only half (50.8%) with ordered computed tomography scan were able to complete the ordered imaging. From these imaging findings, 123 patients (9.6%) were diagnosed with hemorrhagic stroke, while the remainder were diagnosed with ischemic stroke or transient ischemic attack vs hypertensive urgency. 32.9% experienced in-hospital mortality, while only 6.5% followed up.
conclusionThis study documents the significant stroke burden in Sierra Leone, much of which is unaddressed due to lack of specialty resources including inadequate community engagement to raise awareness of risk factors and preventative measures. Poor health-seeking behavior and access to medical services also contribute to this burden. These data are imperative to identify systems gaps and help support ongoing capacity building efforts.
