Because of the pathophysiological relationship between VCAM-1 and hyperthyroidism, we grouped all subjects into four groups: low VCAM-1 without hyperthyroidism (n = 142), high VCAM-1 without hyperthyroidism (n = 93), low VCAM-1 with hyperthyroidism (n = 15), and high VCAM-1 with hyperthyroidism (n = 66) according to the hyperthyroid status and the serum VCAM-1 median of 1055 ng/mL. Here, VCAM1 is linked to hyperthyroidism.
