Under-reporting difficulties in seeing among older people with clinically assessed vision impairment: an exploration of 12 surveys from sub-Saharan Africa.
Article in International health, 2025. 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
backgroundIndividuals who do not perceive they have a health problem will not seek care, risking a deterioration of health status. We sought to understand how visually impaired individuals aged ≥50 y from 12 studies across sub-Saharan Africa self-reported their difficulties seeing, and to identify the factors associated with under-reporting.
methodsWe used R software to assess overall agreement between self-report and clinical assessment with a weighted kappa, and described the proportion of individuals accurately reporting, over-reporting and under-reporting their difficulties seeing. We used logistic regression to explore factors associated with under-reporting.
resultsIn total, 5777/32 548 participants had moderate vision impairment (VI) or worse. Overall, agreement between clinically diagnosed VI and self-reported difficulties seeing was 0.41; 74.7% of participants self-reported a level of difficulty seeing that corresponded with their clinical VI but this varied significantly: individuals with no VI reported most accurately (83.8%), and blind individuals least accurately (18.7%). Individuals were less likely to under-report if they had other self-reported functional difficulties, 'other' primary causes of VI (compared with cataract), or were from certain locations. Individuals with unaddressed refractive error were more likely to under-report.
conclusionsHealth planners need to design programmes to reach individuals who are less likely to perceive they have eye health problems. CONTEXTE: Les personnes qui ne se rendent pas compte qu'elles ont un problème de santé ne consultent pas, ce qui peut entraîner une détérioration de leur état de santé. Nous avons cherché à comprendre comment les personnes malvoyantes âgées de 50 ans et plus inclues dans 12 études menées en Afrique subsaharienne ont auto-déclaré leurs difficultés à voir, et à identifier les facteurs associés à la sous-déclaration.
