1 · What the graph read from it

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.

2 · The registry

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

Objective: This study aimed to compare lung cancer incidence, hospitalisation and mortality rates among municipalities of Rio Grande do Sul from 2000 to 2021 based on estimated radon gas exposure. Methods: An ecological time series study was conducted using data from the Brazilian Geological Survey and the Ministry of Health. Geoprocessing techniques and Prais-Winsten regression were employed for data analysis. Results: No statistically significant differences were found in average outcome rates across the study period when grouped by radon exposure probability. Municipalities with higher exposure probabilities showed an increasing trend in lung cancer incidence and hospitalisation rates, while mortality remained stable. Additionally, hospitalisation rates increased in municipalities with lower exposure probabilities. Conclusion: This study demonstrated the methodological challenges of investigating the association between gases and cancer etiology.
