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

Table 4

The results of multiple linear regression in ESRD patients showing the associations between the redox and nutritional parameters that were independent of covariates. Standardized beta coefficients (95% confidence intervals) and values were shown for dependent variables, and the coefficients of determination () were shown for the models.
