Iodine from food and adverse pregnancy outcomes in non-users of iodine-containing supplements. Sample size: intrauterine death n = 49,187 (0.35% intrauterine deaths), preeclampsia n = 49,187 (3.8% preeclampsia), and preterm delivery n = 48,981 (5.0% preterm and 0.84% early preterm). The associations were modelled by logistic regression adjusting for maternal age, BMI, parity, education, smoking in pregnancy, energy intake, and fibre intake. For the crude associations, see Additional file 1: Figure S3
