Correlation coefficients between TBII activities and clinical parameters in sub- groups classified by the characteristics of TSHRAbs in patients with Graves’ disease

Patients	TBII activity vs. goiter size	TBII activity vs. serum T3	TBII activity vs. serum fT4
Group 1 (n=41)	0.38 (p<0.01)	0.37 (p<0.01)	0.43 (p<0.01)
Group 2 (n=16)	0.52 (p<0.05)	0.48 (p<0.05)	0.38 (p<0.07)
Group 3 (n=19)	-	-	-
Group 4 (n=30)	-	-	-
Group 5 (n=14)	-	-	-
Group 6 (n=10)	-	-	-
Group 7 (n=6)	-	-	-

Categorization of patients into the 7 groups was the same as that in Table 5.

Values are Pearson’s correlation coefficients (R).

‘-’ means no significant correlation between variables.
