Spatial analysis of meningococcal c vaccination coverage in children in BRAZIL between 2012 and 2024.
Article in BMC pediatrics, 2025. 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
The objective is to analyze Meningococcal C conjugate vaccine (MenC) vaccination coverage based on the temporal trend of MenC vaccination coverage over 13 years and its spatial distribution, based on the identification of spatial clusters. This mixed ecological study was performed with secondary data on MenC vaccination coverage from 2012 to 2024 in Brazil. Descriptive analysis was used to assess annual MenC vaccine coverage based on geographic region and years analyzed. The Prais-Winsten linear regression model was used for trend analysis purposes: MenC vaccination coverage by state and region of Brazil was used as a dependent variable and the years analyzed as an independent variable. Spatial dependence and the incidence of spatial clusters formed by municipalities with high and low MenC vaccination coverage were evaluated using spatial statistical analysis. The results of this study showed that vaccination coverage remained stable in Brazil. Among the regions, downward trends were observed in the Southeast and South regions. At the state level, statistically significant reductions were observed in Goiás, Roraima, and Santa Catarina. In addition, it was possible seeing progressive increase in spatial clusters with low vaccination coverage, mainly in Northern and Northeastern Brazil, between 2012 and 2024. These findings are expected to influence the formulation of practices, policies, programs and actions based on robust scientific evidence on the development of strategies and interventions for the prevention and health promotion of meningococcal disease at national and global levels.
