Results which are significantly different (nonparametric unpaired t test), with (P<0.05)

a. Number of denaturing gel electrophoresis (DGGE) bands produced by each sample.

b. Shannon diversity index (H¹) was calculated using the relative intensities of all DGGE bands in each sample.

c. Dice similarity coefficients comparing DGGE band profiles within individual of a given group.

d. Dice similarity coefficients comparing DGGE band profiles between members of Graves' disease and healthy group.
