Redox Balance Correlates with Nutritional Status among Patients with End-Stage Renal Disease Treated with Maintenance Hemodialysis

Table 3

Differences between ESRD patients and controls assessed by logistic regression adjusted for sex, age, and CRP. Odds ratios (OR) for being in the study group are reported with 95% confidence intervals (CI).

	Adjusted for sex and age		Adjusted for sex, age,and CRP
	OR (95% CI)		OR (95% CI)
Glutathione peroxidase (per 1 U/L)	0.94 (0.92; 0.98)	≤0.001	0.97 (0.95; 0.98)	≤0.001
Glutathione reductase (U/L)	0.99 (0.97; 0.998)	0.021	1.00 (1.98; 1.02)	0.7
FRAP (mmol/L)	0.10 (0.01; 0.64)	0.016	0.44 (0.06; 3,14)	0.4
Uric acid (per 10 μmol/L)	1.07 (1.02; 1.12)	0.011	1.01 (0.96; 1.06)	0.7
Superoxide dismutase (U/mL)	0.98 (0.95; 1.02)	0.3	0.91 (0.85; 0.97)	0.003

CRP—C-reactive protein; FRAP—ferric reducing antioxidant power.
