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
objectiveTo analyze the correlation between vaccination coverage against meningitis C and epidemiological indicators of morbidity and mortality associated with the disease in Brazilian pediatric populations aged 3 months to 14 years.
methodsThis descriptive and exploratory epidemiological study used secondary data from the National Immunization Program Information System (SI-PNI) and Notifiable Diseases Information System (SINAN). The analysis covered the period from 2010 to 2024, and examined the relationship between vaccination coverage and the number of meningitis cases and related deaths. The data included variables such as sex, age group, vaccine dose, incidence, mortality, and geographic distribution. Descriptive statistics, including calculations of proportions and rates, were performed using Microsoft Excel® (2019).
resultsFollowing the introduction of the meningitis C vaccine in the National Immunization Program in 2010, the incidence of the disease in Brazil decreased significantly. From 2010 to 2015, the number of confirmed cases decreased by approximately 81%, reaching the lowest recorded rate in 2021 (0.02 per 100,000 inhabitants), representing a 98% reduction. However, an increase in the incidence was observed in 2022 (0.05 per 100,000 inhabitants). Although vaccination coverage exceeded 95% in 2011, it has declined in subsequent years.
conclusionThe meningitis C vaccination program has had a positive impact on public health, contributing to a marked reduction in disease cases and related deaths since its implementation. Higher vaccination coverage was associated with lower morbidity and mortality rates.
