Prevalence of dementia among older persons in Northern Uganda, a cross-sectional study.
Article in African health sciences, 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: The burden and clinical correlates of dementia are unknown in Uganda. We therefore determined the prevalence and factors associated with dementia among older persons in Northern Uganda. Methods: In a cross-sectional study, adults aged 60 years and above attending the medical outpatient clinic at a tertiary Hospital from March 2022 to April 2022 were enrolled. The prevalence of dementia was determined using the Intervention for Dementia in Elderly Africans (IDEA) and the Instrumental Activities of Daily Living (IADL) tool henceforth presented as IDEA-IADL. Factors of association were collected using a standardized questionnaire. Results: A total of 271 eligible participants were enrolled into the study. Majority were age 60-69 years (153/271) and of male gender (165/271). The prevalence of dementia was 17.7% (48/271), severe dementia 7.4%, (20/271), moderate dementia 10.3%, (28/271). Factors independently associated with dementia were: participants aged between 80-89 years; (adjusted odds ratio (aOR): 9.7; 95% Confidence Interval (CI): 4.08-23.07, p< 0.001), family history of dementia (aOR: 3.4, 95CI: 1.62-7.04, p=0.001). history of depression (aOR: 2.7, 95CI: 1.40-5.02, p=0.003). Physical activity and cognitive exercise were associated protective factors with (aOR 0.1, 95CI: 0.03-0.24, p< 0.001) and (aOR 0.2, 95CI: 0.06-0.53, p<0.002) respectively. Conclusion: There burden of dementia among older persons in Northern Uganda is significant. Enhanced screening and early identification of dementia is recommended in this setting.
