Temporal trend and spatial analysis of breast cancer mortality in Paraná, 2012-2021.
Article in Epidemiologia e servicos de saude : revista do Sistema Unico de Saude do Brasil, 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
objectivesTo analyze the temporal trend and identify spatial clusters of breast cancer mortality in Paraná state between 2012 and 2021.
methodsThis was a time series study, with spatial analysis of breast cancer mortality rates in the 399 municipalities of Paraná. Data were selected from the Mortality Information System. Time series analysis was performed using the Prais-Winsten autoregression method. The Getis-Ord Gi* technique was used to identify spatial clusters.
resultsA total of 8,819 breast cancer deaths were reported, with a rising trend in Paraná (annual percentage change [APC] +1.83; 95% confidence interval [95%CI] 0.86; 2.82). The East macro-region of the state stood out (APC +4.27; 95%CI 2.27; 6.32). Spatial analysis showed areas with a higher standardized mortality rate in the West and North macro-regions and areas with a lower rate in the East macro-region.
conclusionIn the period 2012-2021, there was an increase in breast cancer deaths in Paraná. Trend analysis showed that the phenomenon grew mainly in the East macro-region. In the spatial analysis, the West and North macro-regions had the highest concentration of the event. These results indicate areas in need of immediate intervention in the state.
