Fig. 1From: Urinary iodine in early pregnancy is associated with subclinical hypothyroidism in Tianjin, China: an observational studyUrinary iodine concentration (UIC) distribution among early pregnant women with euthyroidism and subclinical hypothyroidism in Tianjin.

The percentage of those with UIC ≥ 250 μg/L in the SH group was significantly higher than that in the EH group (χ2 = 8.265, p = 0.004)Back to article page
