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 this study was to investigate the association between pneumoniarelated mortality and morbidity and urban, environmental, and socioeconomic conditions in the administrative districts of São Paulo, Brazil.
methodsWe conducted an ecological study using aggregated data from 2010 to 2020 across 96 administrative districts in ã Paulo. Mortality and hospitalization data for individuals up to 19 years old were analyzed in relation to the Geographic Index of the Socioeconomic Context for Health and Social Studies (GeoSES), housing standards, and urban conditions. Spatial analysis involved estimating relative risk using SaTScan, and Ordinary Least Squares (OLS) and Geographically Weighted Regression (GWR) were applied to assess spatial associations.
resultsBetween 2010 and 2020, 1486 deaths and 1,56,112 hospitalizations due to pneumonia were recorded among individuals up to 19 years old. Mortality was higher among males (54.7%) and displayed spatial clustering. Mortality rates were negatively associated with the proportion of high-standard residences and the GeoSES index and positively associated with the presence of rapid-transit roadways. The GWR model outperformed the OLS model (adjusted R2=0.44 vs. 0.40) for mortality. Hospitalization rates were more uniformly distributed and showed a weaker association with socioeconomic indicators (adjusted R2=0.17 for OLS).
conclusionsPneumonia mortality among children and adolescents in São Paulo is spatially associated with socioeconomic and urban conditions. These findings underscore the need for geographically targeted public health interventions that address urban planning and social inequalities in disease prevention strategies.
