Spatiotemporal trends in hospital morbidity indicators due to road traffic injuries in the state of Piauí, Brazil, 2010-2023.
Article in Revista brasileira de epidemiologia = Brazilian journal of epidemiology, 2026. 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
objectiveTo analyze spatiotemporal trends in hospital morbidity indicators for road traffic injuries in the state of Piauí, Brazil, from 2010 to 2023.
methodsThis is an ecological, time-series and spatial analysis using data from the Hospital Information System of the Brazilian Unified Health System. Trends in hospitalization rates, according to health regions and sociodemographic characteristics, were analyzed using annual percent change (APC) and 95% confidence intervals (95%CI), estimated by Prais-Winsten regression. Spatial clusters were identified at the municipality level using Local Indicators of Spatial Association (LISA) maps.
resultsA total of 80,251 hospitalizations due to road traffic injuries were recorded. The mean hospitalization rate was 176.1/100 thousand inhabitants, showing an increasing trend (APC 5.72; 95%CI 1.04; 10.61), while case fatality (2.3%) remained stable (APC -2.42; 95%CI -5.07; 0.30). The mean hospitalization cost per admission (BRL 1,123.92) showed a decreasing trend (APC -3.17; 95%CI -5.57; -0.71), whereas the mean length of hospital stay (4.9 days) remained stable (APC -1.07; 95%CI -2.96; 0.86). High-high spatial clusters of hospitalization rates were observed in municipalities located in the Northern and Southern regions of the state.
conclusionHospitalization rates for road traffic injuries increased in Piauí, followed by a reduction in mean cost and stability in case fatality and length of hospital stay. Higher morbidity was concentrated in the Northern and Southern regions, suggesting a geographic shift of hospital morbidity toward inland areas.
