The Claim
Thyroid ultrasonography screening in asymptomatic adults is not associated with a reduction in death from thyroid cancer, based on findings from a case-control study conducted in Korea involving 120 thyroid cancer deaths and 1,184 matched controls, with odds ratios of 1.44 (95% CI 0.68–3.05) and 1.13 (95% CI 0.49–2.63) under different data handling methods, and no statistically significant associations observed across subgroups.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Getting an ultrasound of the thyroid if you have no symptoms doesn’t seem to help people live longer or prevent them from dying of thyroid cancer, according to a study in Korea.
See the scientific wording
Thyroid ultrasonography screening in asymptomatic adults is not associated with a reduction in death from thyroid cancer, as observed in a case-control study of 120 thyroid cancer deaths and 1,184 matched controls in Korea, with odds ratios of 1.44 (95% CI 0.68–3.05) and 1.13 (95% CI 0.49–2.63) depending on data handling, and no statistically significant relationships found across subgroups.
What the research says
1 studyThis study looked at whether checking people's thyroids with ultrasound saves lives, and found no evidence that it does — people who got screened were no less likely to die from thyroid cancer than those who didn't.
