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

What is already known about this topic?: Indoor radon is the second leading cause of lung cancer after smoking, but previous studies in China have mainly focused on urban areas, with limited data from rural areas. What is added by this report?: A survey of 20 cities from 2023-2025 shows that median indoor radon concentrations in rural areas (72 Bq/m3) are higher than in urban areas (65 Bq/m3). Higher levels are also associated with northern regions, low floor levels, brick-wood structures, and energy-efficient buildings. What are the implications for public health practice?: It is recommended to control radon release from building materials at the source, improve ventilation, seal cracks in walls and floors, and pay attention to rural and cold climate regions.
