Prevalence of Periodontitis in Africa: A Systematic Review and Meta-Analysis of Epidemiological Studies Up to 2025.
Synthesis in Journal of clinical periodontology, 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
aimTo provide updated and comprehensive estimates of the changes in prevalence of periodontitis in Africa, based on epidemiological data up to 2025.
methodsA systematic literature search was conducted through MEDLINE, Embase, Scopus, Web of Science and Google Scholar. Meta-analyses were performed to estimate the prevalence of periodontitis across population subgroups and diagnostic criteria.
resultsTwenty-three studies met the inclusion criteria. Among children (< 10 years), prevalence was 1.9% (95% CI: 0.9%-3.9%; I
conclusionEpidemiological studies on periodontitis in Africa often overrepresent younger populations and rely on non-confident diagnostic criteria, likely underestimating true prevalence. Nevertheless, updated estimates suggest a concerning burden among younger age groups. More comprehensive research is needed to enhance the accuracy of prevalence estimates of periodontitis in Africa.
