The prevalence and determinants of epilepsy in Ghana: A population-based study in two districts using a three-stage approach.
Article in Epilepsia, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectiveEpilepsy imposes a disproportionate burden in Africa, yet there are no reliable epidemiological data from Ghana. This community-based cross-sectional survey addressed this gap in southeastern Ghana, incorporating an analytical comparison of confirmed cases and age- and sex-matched controls.
methodsWe conducted a population-based cross-sectional study using a validated tool and a three-stage screening approach to estimate the prevalence of active epilepsy in the two Ghanaian districts of Shai-Osudoku and Ningo-Prampram. The three-stage approach consisted of population screening, detailed individual assessment, and clinical confirmation by specialists. To identify factors associated with epilepsy, we conducted a cross-sectional analysis comparing confirmed cases with age- and sex-matched controls randomly selected from the same population. Trained fieldworkers administered standardized questionnaires to capture sociodemographic data and historical risk exposures.
resultsThe attrition-adjusted prevalence of active epilepsy was 8.84 per 1000 people (95% confidence interval [CI]: 8.00-9.68), higher in Shai-Osudoku (12.30 per 1000) than in Ningo-Prampram, and greatest in remote rural areas. Prevalence was higher among males (10.53 per 1000) and peaked at ages 20-29 years (11.44 per 1000). The poorest quintile had a prevalence three times that of the wealthiest. In children (≤16 years), fever-related convulsions (adjusted odds ratio [aOR] = 94.75; 95% CI: 17.40-515.96; p < .001) and history of cerebral/severe malaria (1.03; 95% CI: 1.01-1.06; p = .003) were strongly associated with epilepsy; younger males had higher odds (2.78; 95% CI: 1.12-6.88). In adults, household members with epilepsy (6.21; 95% CI: 2.56-15.11), family history (3.55; 95% CI: 1.13-11.19), head injury (24.45; 95% CI: 3.07-194.60), and household ownership of cats (1.76; 95% CI: 1.10-2.81) or pigs (2.26; 95% CI: 1.10-4.66) were significant risk factors. SIGNIFICANCE: Our findings highlight a high burden of epilepsy in southeastern Ghana, with variations observed across geographic, demographic, and socioeconomic groups. Modifiable risks such as head injury and cerebral or severe malaria highlight urgent needs for targeted prevention, improved health care access, and poverty alleviation strategies.
