Data are presented as mean values ± standard error of the mean (SEM).

P < 0.01 for the comparison between the baseline and post-surgery follow-up mean values by paired sample t-test or Wilcoxon signed-rank test.
a
Mean echogenicity (density) of the thyroid parenchyma in gray-scales relative to the muscle echogenicity, as determined by the gray-scale histogram analysis on the thyroid ultrasound scanning.
BMI, body mass index; WC, waist circumference; TSH, thyroid-stimulating hormone; fT4, free-T4; fT3, free-T3; rT3, reverse-T3.
