Association of Socioeconomic Status and Oral Cancer Mortality in Brazil: Temporal Trends and Spatial Distribution.

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 objective of this observational study was to evaluate the relationship between the oral cancer mortality rate and socioeconomic indicators throughout the Brazilian territory, between 2010 and 2019.
methodThe variables used in this study were oral cancer mortality rates from the Mortality Information System (SIM) and population data from the Brazilian Institute of Geography and Statistics (IBGE) to calculate oral cancer mortality rates, along with the Human Development Index (HDI) and Social Vulnerability Index (SVI). The analysis was performed in tertile stratifications (Microsoft Excel 16.0), while temporal trends were examined by segmented linear regression (JoinPoint 4.9.0).
resultsHigh mortality rates were observed in more developed regions (South and Southeast), whereas temporal analysis showed significant increasing trends in the North (annual percentage changes [APC] = +3.9%; p < 0.05) and Northeast (APC = +2.4%; p < 0.05) regions. The greater HDI (APC = +1.7%; p < 0.05) and SVI (APC = +2.2%; p < 0.05) tertiles had the lowest annual percentage increase, showing an inverse relationship between the temporal trend of mortality and socioeconomic indicators.
conclusionDespite the higher number of oral cancer deaths in regions with higher social indices, increasing temporal trends are more accentuated in regions with lower socioeconomic levels.
