Prevalence of eye diseases among prison inmates in Sub-Saharan Africa: a systematic review and meta-analysis protocol.
Article in Frontiers in medicine, 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: Eye diseases constitute a major public health challenge globally, with a disproportionate burden borne by populations in low- and middle-income countries (LMICs), including Sub-Saharan Africa (SSA). Prison populations represent a uniquely vulnerable group characterized by restricted access to healthcare, overcrowding, poor nutrition, and high-risk environmental conditions - all of which substantially elevate the risk of eye diseases. Despite individual country-level reports documenting elevated rates of eye disease among incarcerated persons in SSA, no synthesis of the evidence has been conducted. This systematic review and meta-analysis protocol aims to consolidate existing evidence on the prevalence of eye diseases among prison inmates across SSA. Methods: The protocol has been developed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P) guidelines to ensure rigor, transparency, and reproducibility. We will search major databases, including PubMed, Scopus, Web of Science, Embase, CINAHL (via EBSCO), PsycINFO, Google Scholar, and African Journals Online, using controlled vocabularies without date or language restrictions. Risk of bias and study quality will be assessed using standard critical appraisal tools. The completed review will follow the PRISMA reporting checklist and where appropriate, a meta-analysis will be conducted to generate pooled estimates, with subgroup analyses to explore sources of heterogeneity and country-level variations. Discussion: Given the eye's role as a non-invasive window into systemic and overall health, findings from this review may inform evidence-based screening strategies and support policy reforms aimed at improving ocular and general health care in prison settings.
