Tg in Adults as a Sensitive Biomarker of Iodine Status: A 5-Year Follow up Population Study in Different Levels of Iodine Intake Regions
Fig 1
Serum Tg (ng/mL) in 1999,2004 and the 5-year changes of serum Tg (ΔTg) among different iodine status (n = 1856).
1856 subjects who had negative TgAb, normal TV and TSH, and negative personal history of thyroid diseases were from three levels of iodine status. Data were expressed as median + 1/2 interquartile range. * denotes a substancial difference among three levels of iodine status in 1999 (P<0.0001). & denotes a substancial difference among three levels of iodine status in 2004 (P<0.0001). # denotes a substancial difference of 5-year changes of Tg among three levels of iodine status (P = 0.0021).
