Analysis of Morbidity and Mortality Due to Yellow Fever in Brazil.
Article in Viruses, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
introductionYellow fever (YF) is a viral hemorrhagic fever transmitted by mosquitoes, characterized by a high mortality due to kidney and liver failure, massive coagulation disorders, and hemorrhages. With no specific treatment, prevention through vaccination and vector control is essential. This study investigates the epidemiology of YF in Brazil from 2011 to 2020, focusing on its trends and distribution across the territory.
methodsThis ecological time-series study analyzed confirmed YF cases in Brazil's 27 federative units between 2011 and 2020. Data were sourced from DATASUS, IBGE, and IPEA. Incidence rates per 100,000 inhabitants were calculated, and various sociodemographic and health indicators were analyzed. Prais-Winsten autoregressive models assessed the trends, while a spatial analysis identified the risk areas using global and local Moran's I statistics. The data were processed using Stata and GeoDa
resultsYF cases were concentrated in the Amazon and Atlantic Forest biomes. The majority of the cases occurred in males (83.3%), non-white individuals (94.3%), and rural workers. Pará showed an increasing trend in incidence. A higher vaccination coverage correlated with a lower YF incidence, though endemic areas with good vaccination coverage still exhibited high rates. Health and socioeconomic indicators were inversely related to incidence, highlighting disparities in regional development.
conclusionEffective YF control requires multidisciplinary strategies, including expanded vaccination coverage, intensified vector control, and active surveillance. Research should focus on developing better vaccines, monitoring immunity, and improving the global response coordination.
