Prevalence of Strongyloides stercoralis infection among African children: A systematic review and meta-analysis.
Synthesis in PLoS neglected tropical diseases, 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
Strongyloides stercoralis is a neglected parasite that causes strongyloidiasis. However, the true prevalence of strongyloidiasis is underreported due to low-sensitivity diagnostic methods. This systematic review assessed the prevalence of S. stercoralis among African children and its variation by diagnostic methods, countries, and study settings. All studies published in African countries on S. stercoralis prevalence up to the year 2025 in the PubMed, Google Scholar, Scopus, and ScienceDirect databases were included. Identification, screening, checking the eligibility, and including the relevant studies were done following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Out of 651 articles screened, 27 studies involving 16,358 children were included in the systematic review. The pooled prevalence of S. stercoralis among African children was 14% using a random-effect model. The highest pooled prevalence of S. stercoralis was recorded at 27% in Côte d'Ivoire, followed by 26% in Ethiopia. A high prevalence (36%) of S. stercoralis was obtained by a combination of PCR, culture, and microscopic diagnostic methods. This review indicated that S. stercoralis prevalence in African children is considerable and likely underestimated due to low-sensitivity diagnostics. Therefore, further studies using sensitive diagnostic approaches are urgently needed to determine the true burden of strongyloidiasis.
