Fig. 8: Thyroid function polygenic risk scores and the risk of thyroid cancer.

Plots of the associations between thyroid parameter polygenic scores TSH (panel a) and FT3 (panel b) and thyroid cancer in deCODE (a; Ncase = 620, Ncontrol = 106,168, b; Ncase = 686, Ncontrol = 119,187). The y-axis shows the probability of thyroid cancer. The x-axis shows the percentage of risk alleles carried out based on a weighted polygenic score. The histogram shows the distribution of the polygenic score in the study sample per trait. Ncase: sample size of cases. Ncontrol: sample size of controls.
