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

backgroundLung cancer is the leading cause of cancer-related mortality in the United States. While smoking cigarettes remains the dominant risk factor, declining smoking rates have drawn attention to Radon. Despite the known risks from individual exposure to radon, how long-term lung cancer trends vary by county-level Radon risk classification remains unknown.

methodsUsing SEER-8 cancer registry data from Connecticut, Iowa, New Mexico, and Utah, we compared lung cancer incidence between counties classified by the EPA as low-risk and high-risk (>4.0 pCi/L) for radon exposure. Constructing a random effects Generalized Least Squares regression, which adjusted for county-level smoking prevalence, we quantified the excess lung cancer rate attributable to radon risk across decade, sex, and histologic subtype.

resultsCompared to low-risk counties, counties at high risk of radon exposure had a significantly higher overall lung cancer incidence: 13.5 + cases per 100,000 person-years (95% CI: 10.0, 17.1). This gap between low and high-risk counties was largest for Adenocarcinoma and small cell carcinoma, and larger in males than females. However, only in females did we observe the gap in lung cancer incidence between low- and high-risk counties grow decade after decade.

conclusionsThis study illustrates how county-level radon data can be leveraged to enhance cancer surveillance and guide prevention and control strategies. Further research is needed to evaluate the impact and cost-effectiveness of radon prevention or mitigation policies, especially in females. We argue that public health systems, over the next fifty years, must prioritize eliminating the two main drivers of America's deadliest cancer.
