The Prevalence of Nutritional Anaemia in Brazilian Pregnant Women: A Systematic Review and Meta-Analysis.
Synthesis in International journal of environmental research and public health, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled it.
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
Despite the global tendency of maternal anaemia to decline, the persistence of anaemia in Brazil is an important health problem given its vulnerability to deficiencies and the significant increase in nutritional requirements during pregnancy. The aim of this study was to estimate the prevalence of anaemia in Brazilian pregnant women through a systematic literature review and meta-analysis. The systematic review was carried out according to Systematic Reviews and Meta-Analyses PRISMA checklist recommendations and using the following electronic databases: Medline, Scopus, Embase, Web of Science, Lilacs, Scielo, Google Scholar, and CAPES Catalog of Theses and Dissertations. Studies that presented a prevalence of anaemia data in Brazilian pregnant women, considering all gestational trimesters, were included. The total sample included 12,792 pregnant women covering all gestational trimesters. The pooled prevalence of anaemia in Brazilian pregnant women was 23% (95% CI: 20-27), with the highest prevalence in the Northeast Region at 26% (95% CI 23-29), while the lowest prevalence was observed in the North Region with 17% (95% CI 14-20). Among the subgroups, no statistical difference was observed. The prevalence of anaemia status in Brazil is still classified as a moderate public health problem according to the World Health Organization maternal anaemia classification.
