Magnitude and predictors of mild cognitive impairment among older populations in Africa: a systematic review and meta-analysis.
Synthesis in Translational psychiatry, 2025. 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
backgroundWith an increasingly older population, age-related health issues such as mild cognitive impairment and dementia are serious public health concerns. Emerging data suggest that public health and preventative intervention strategies can modify early risk factors for the development of mild cognitive impairment and dementia. However, there is inadequate evidence of mild cognitive impairment in older populations in Africa. Therefore, this review aimed to provide pooled evidence of mild cognitive impairment among older populations and its predictors in Africa.
methodsAll the available primary studies were searched through Google Scholar, HINARI, PubMed, Psych Info, CINAHL, Embase, Web of Science, and Cochrane Library databases. The quality of the included studies was critically appraised by the Joanna Briggs Institute (JBI) assessment tool adapted for observational studies. All the data were extracted on an Excel spreadsheet and exported to Stata version 17. During critical appraisal, disagreements between the two authors were resolved by the involvement of a third author. Effect sizes were pooled using the random-effects model, and the presence of publication bias was detected from the asymmetry of the funnel plot and statistically significant Egger's test (p < 0.05).
resultsThe pooled magnitude of mild cognitive impairment among older populations was 29.39% (95% CI:24.73, 34.04, I
conclusionsThe magnitude of mild cognitive impairment among Africa's older populations is significant. This suggests that cognitive disorders should be routinely screened among older people who visit healthcare facilities regarding physical health to enable early detection and treatment of reversible causes of neurocognitive impairment. Furthermore, identifying modifiable factors would inform evidence-based policies to reduce the health and societal burden of cognitive decline.
