Effects of non-ionizing radiation on the thyroid gland in rats.
Article in BMC research notes, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectivesThis study evaluated the effects of non-ionizing electromagnetic radiation on rat thyroid function and histopathology. Forty female and thirty male Sprague-Dawley rats (200-220 g, 2 months old) were exposed to 2.45 GHz Wi-Fi, mobile jammer radiation, or a sham condition. In Group A, male rats were exposed to Wi-Fi or mobile jammers for 2 h daily for two weeks. The devices were located within a one-meter radius of the animal cage, either on or off. In the Sham group, the experimental setup was like the other groups, but the irradiating devices were turned off. Group B included non-pregnant females, pregnant (exposed and control subgroups), and their offspring. Thyroid hormones in the serum were measured, and the histology was microscopically analyzed, focusing on areas of colloid and epithelium in the thyroid follicles.
resultsCompared to the control group, T4 hormone levels were significantly different in male rats exposed to mobile jammer radiation (p-value = 0.037). In group B, significant differences were found solely in the male offspring regarding T3 levels due to jammer exposure (average = 109.00 for male offspring in the experiment vs. average = 65.50 for those in the control, p-value < 0.001). Additionally, histopathological findings indicated significant differences as well. These results highlight a potential link between exposure to electromagnetic radiation and changes in thyroid endocrine and histological parameters. Our findings suggest that ongoing assessment of existing safety guidelines on non-ionizing radiation exposure is necessary, especially concerning its effects on thyroid hormone levels and follicular histology.
