Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
group with normal T4 level or T4/T3
participants with T4 within 4.3-12.5ug/dl and ratio of T4/T3(T4(ug/dl)/T3 (ng/ml)) ≤7.52, which are considered to be normal T4 level and T4/T3.
detection of serum selenium
For this case-control study, no intervention will be administered to participants, only serum sample will be collected for selenium assessment
group with elevated T4 level or T4/T3
participants with T4 more than 12.5ug/dl and ratio of T4/T3(T4(ug/dl)/T3 (ng/ml)) \> 7.52, which are considered to be elevated T4 level and T4/T3.
