Values of TSH and T4 are mean (SD); all other values are numbers of affected/non-affected. p Values are for comparisons between 2268insT(+) and 2268insT(−). Comparisons of differences among three groups, p<0.0001 for TSH; p  =  0.409 for T4.
*Measured at initial confirmatory diagnosis; †measured after T4 withdrawal.
