Table 4 Comparison of the activities of enzymatic antioxidants (Catalase, GR and TAOC) in plasma among the groups

Groups Value	Patients	Controls	P value	95%CI
Groups Value	Values		P value	95%CI
Plasma catalase (ku/l)	1.95 ± 0.40	13.38 ± 10	0.001	5.49–8.46
Plasma GR (nmol/min/ml)	28.55 ± 10.79	48.72 ± 8.02	0.001	33.91–38.72
Plasma TAOC (mM trolox equivalent)	2427 ± 520.31	4192 ± 465	0.002	2933.42–3279.01

Patients, n = 80; Controls, n = 50. Normally distributed data are expressed as means±SD, and non normally distributed data are expressed as median (IQR [interquartile range]). GR Glutathione reductase, TAOC Total antioxidant capacity. The difference is significant compared with the control group (P ≤ 0.05)
