Low back pain prevalence across African populations from 2017 to 2025: a systematic review and meta-analysis.
Synthesis in Frontiers in public health, 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: Occupational low back pain (LBP) represents a major and under-characterized health burden among African workers. While pan-continental LBP prevalence data exist for the general population, occupationally stratified meta-analytic estimates have never been produced for the full African continent. Evidence from Africa remains fragmented, with no existing review integrating occupational, general population, and pregnancy-related LBP within a single pan-continental synthesis. This systematic review and meta-analysis aimed to generate the first occupationally stratified pooled prevalence estimates of LBP across African populations and to update continental prevalence figures from studies published between 2017 and 2025. Methods: A systematic review and meta-analysis was conducted following PRISMA 2020 guidelines. Seven bibliographic databases and two regional indexes (nine information sources in total) were searched for studies published between May 2017 and August 2025. Eligible studies reported point, 12-month, or lifetime LBP prevalence in African populations. Methodological quality was assessed using a validated 10-item appraisal tool. Random-effects meta-analyses used restricted maximum likelihood (REML) estimation with Hartung-Knapp adjustment to provide conservative 95% confidence intervals. Certainty of evidence was assessed using the GRADE approach. Results: Twenty-six studies from fifteen African countries involving 14,339 participants were included (sample size was reported in 25 of the 26 studies). Overall pooled prevalence estimates were 53% (95% CI 40-65%; Conclusions: Low back pain represents a substantial and unevenly distributed health burden across African populations, with particularly high prevalence in occupational groups exposed to physical workload. These findings highlight the need for strengthened surveillance, workplace prevention strategies, and integration of musculoskeletal care into primary and occupational health services in African settings.
