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
Objective: This study aims to evaluate the activity concentrations of natural radionuclides in major edible crops from Hainan Island, quantify the annual effective dose and lifetime cancer risk (ELCR) caused by dietary intake, and provide a scientific basis for local food safety regulation and radiation protection strategies. Methods: Sixteen representative crop samples (12 vegetables, 4 grains) were collected in 2025. High-purity germanium gamma spectrometry (HPGe) was used to measure the activity concentrations of Results: Radionuclide activities followed the order Conclusion: The radioactivity levels in Hainan crops are generally safe, and the radiation risk from dietary intake is within acceptable limits. Children require particular attention due to differences in metabolism and consumption rates. Long-term monitoring is recommended, especially for staple crops like rice, and further research should track the impact of agricultural practices on radionuclide migration.
