FIG. 3. — Adjusted associations between UIC (column 1; n = 2900), creatinine-adjusted UIC (column 2; n = 2900), and iodine from food (column 3, restricted to nonusers of iodine supplement; n = 1730) and TSH, FT4, and FT3. For TSH, the geometric mean was modelled (by square root transformation), and for FT3 and FT4, the highest first percentile was excluded to obtain ∼normal distribution. Including the upper first percentile of FT3 and FT4 did not change the results (Supplementary Fig. S5). FT3, free triiodothyronine.
