	Cycle 3 - Data for age group 20-39 (All - no exclusions)

	Males	Females
TSH (mIU/L)	1.53	1.80
FT4 (pmol/L)	15.5	14.1
UFUC Fluoride adjusted for urine creatinine (µmol/mmol)	2.0	2.80

		Numerous age groups are available from the Cycle 3 data set. As TSH values change with age, gender (puberty), diabetes, etc., we have taken here the most stable age group (age 20 to 39).
