Insulin resistance in H pylori infection and its association with oxidative stress

Table 2 Oxidative and antioxidative parameters in H pylori positive and negative groups (mean ± SD)

	H pylori negative(n = 48)	H pylori positive(n = 55)	P
TAC (mmol Trolox eq./L)	1.70 ± 0.50	1.36 ± 0.33	< 0.001
TOS (μmol H2O2 equiv./L)	5.08 ± 0.95	6.79 ± 3.40	< 0.001
OSI (arbitrary unit)	3.10 ± 0.92	5.42 ± 3.40	< 0.001

TAC: Total antioxidant capacity; TOS: Total oxidant status; OSI: Oxidative stress index.
