Assessing historical residential radon exposure using a glass-based surface trap method in low radon level areas: a pilot study.

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
Retrospectively estimating residential radon exposure in epidemiological studies is challenging using conventional methods. This study aimed to compare a modified glass-based surface trap technique for assessing historical indoor radon exposure with conventional long-term radon detectors among pregnant women from areas with relatively low radon levels. Ten women during their first trimester pregnancy were recruited from a Columbia University Irving Medical Center-affiliated hospital. Each participant was asked to place one detector in the basement and another in a high-occupancy main-floor room until delivery, after which devices were returned by prepaid mail to a certified laboratory. In addition, we collected the cover glass from small picture-frames that participants placed in the main-floor living area of their current and previous homes. Each glass plate was mounted against TASTRAK alpha-particle-detecting plastic and stored at-20 °C in a radon-proof atmosphere for 37 d. Plastics were etched and analysed for alpha-particle track density over a 4 cm
