Fig 6. Scatter plots of predictive AUC on the x-axis versus measured AUC on the y-axis.

The predicted AUC estimated with a multiple regression equation provided the closest approximation to the actual value of AUC_0-12 using the three time points C₂, C₄, and C₆, and almost exactly the same result was obtained using the two time points C₂ and C₆.
