Serum level of TSH in the TBT-treated group compared with the control and the TBT + GTE groups

TSH (μIU/ml)	Control group (n = 15)	TBT treated group (n = 15)	TBT + GTE group (n = 15)	F	p
Min. – Max.	0.11–0.39	2.58–3.18	0.18–2.73	130.483*	<0.001*
Mean ± SD.	0.28 ± 0.09	2.81 ± 0.20	1.65 ± 0.71
Median	0.31	2.77	1.76
Significance between groups	p1 < 0.001*, p2 < 0.001*, p3 < 0.001*

F: F test (ANOVA), Significance between groups was done using Post Hoc Test (LSD)

p₁: p value for comparing between Control and TBT treated groups

p₂: p value for comparing between Control and TBT + GTE groups

p₃: p value for comparing between TBT treated and TBT + GTEgroups

*: Statistically significant at p ≤ 0.05
