Coefficients and standard errors from linear regression analysis assessing the relationship between log β2-microglobulin concentrations as dependent variable and several independent variables are shown.

The coefficients for log age, male gender, and eGFRBIS2, the coefficients were obtained from a model incorporating log eGFRBIS2, log age and gender as independent variables and log β2-microglobulin as dependent variable. This model explained 60% of the variability of log β2-microglobulin. The partial correlation coefficients rpartial are given for significant predictors in the adjusted models and represent the correlation of each variable with log β2-microglobulin, adjusted for the effect of the other variables in the model (i.e. log eGFRBIS2, log age, and gender). P denotes the level of significance for each specific relationship.
