Median (95% CI) UIC in Danish pregnant women, their male partners and children when all individuals performed urine sampling at home under similar conditions. The p value is the result of the Kruskal-Wallis test (UIC pregnant women vs. male partners vs. children). Iodine supplement users: pregnant women (n = 59), male partners (n = 10), children (n = 13). Kruskal-Wallis test (UIC pregnant women vs. male partners vs. children) in iodine supplement users, p = 0.5, and in iodine supplement nonusers, p = 0.4. Data are from Andersen [3] and Andersen et al. [16].
