The treatments had no effect on T3 hormone at Week 4
(P=0.2503), but the effect became significant at Week 6
(P=0.0010). Within week 6, the increasing level of Br (T2
to T3) significantly reduced T3 hormone levels. I (P=
0.0273), irrespective of Br, as well as the interaction between
I and Br (P=0.0019) had an ameliorating effect on the T3
hormone levels (T6 compared with T3) (Table 2).
