Oxidative status markers in patients with autoimmune thyroiditis and healthy controls.

Variables	Patients (n = 32)	Controls (n = 20)
MDA (nmol/ml)	6.9 ± 1.4	4.1 ± 0.9	0.004
TAC (mmol/l)	10.2 ± 2.2	14.1 ± 3.8	<0.001
SOD (U/ml)	70.9 ± 9.5	95.1 ± 16.4	<0.001

MDA: malondialdehyde; TAC: total antioxidant capacity; SOD: superoxide dismutase.
