 A Contour plot of the interaction between DIO1 expression and serum selenium concentrations on mortality. B Cox regression models depicting the association of DIO1 expression with mortality according to 10th, 50th and 90th quantiles of circulating selenium. C Contour plot of the interaction between DIO3 expression and serum selenium concentrations on mortality. D Cox regression models depicting the association of DIO3 expression with mortality according to 10th, 50th and 90th quantiles of circulating selenium. E Contour plot of the interaction between SELENOM expression and serum selenium concentrations on mortality. F Cox regression models depicting the association of SELENOM expression with mortality according to 10th, 50th and 90th quantiles of circulating selenium. All models were adjusted for age, tumour size, histological grade, lymph node involvement, expression of HER2/ER/PGR-Receptor, laterality of the tumour, and histological type
