Figure 1. Diagnostic plots for gabapentin pharmacokinetic final model. (A) Observed vs. population and individual predicted GBP concentrations. Linear regression fit is shown in black, whereas identity line in grey. (B) Population and individual weighted residuals (PWRES and IWRES, respectively) vs. time (upper panels; left) andvs. predictive GBP concentrations (lower panels; left); Normalized and prediction distribution error (NPDE) vs. time and GBP concentrations for the final model (right). The observed data are presented as black circles. (C) Visual predictive check (VPC) plot for the final model. The observed data are presented as black circles. The dashed lines represent the 5th, 50thand 95th percentiles of the predicted data. The grey areas represent the 95% confidence interval of predicted percentiles.
