Comparison of predicted and observed values for PK parameters for metformin
Simulation conditions are listed by rank order according to Σδall. δ is the absolute difference between one and the ratio of the predicted value of the parameter over the observed value, as defined by eq. 6 in the Materials and Methods section. Supplemental Table 39 provides actual parameter estimates as well as δ values.
