Temporal and spatial analysis of visceral leishmaniasis in Brazil, by age group and sex: an ecological study, 2013-2022.

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
objectiveThe aim of the study was to analyze the temporal trend and spatial distribution of the incidence rate of visceral leishmaniasis by age and sex across Brazilian states, macro-regions, and nationally, from 2013 to 2022.
methodsEcological study with temporal and spatial analyses of cases recorded in Brazil's national disease notification system, using Prais-Winsten regression and global and local Moran indices.
resultsA total of 31,453 visceral leishmaniasis cases were recorded in Brazil in the period (mean incidence of 1.68 per 100,000). A statistically significant decreasing trend was observed in Brazil (annual percent change [APC]: -3.25, 95% confidence interval [95%CI] -5.65; -0.79), particularly among women (APC -4.12, 95%CI -6.68; -1.49) and children and adolescents (APC -5.17; 95%CI -8.59; -1.62). An increase was observed among women in Santa Catarina (APC 9.03; 95%CI 6.49; 11.64), in adults in Rio Grande do Sul (APC 7.39; 95%CI 3.47; 11.45) and Santa Catarina (APC 6.48; 95%CI 1.89; 11.27) and in older adults in Paraíba (APC 2.13; 95%CI 0.46; 3.84). Spatial analysis revealed high-risk municipality clusters in the Northeast, North, Midwest, and Southeast, with the highest incidence rate in children and adolescents.
conclusionsdemographic factors such as age range (especially children and adolescents) and sex were associated with a high risk of visceral leishmaniasis, indicating a need for targeted control measures in Brazil.
