Correlation between the observed and predicted values of the dependent variable, multiple correlation coefficient (R2) for the biomarkers of oxidative stress. Multiple linear regression analysis using the "stepwise" procedure; "e" and "p" are measurements performed in erythrocytes and plasma, respectively
