From: Population pharmacokinetic properties of artemisinin in healthy male Vietnamese volunteers
Goodness-of-fit diagnostics of the final model describing artemisinin population pharmacokinetics in healthy male Vietnamese subjects. Open circles represent observed concentrations versus population predicted concentrations (a) and individually predicted concentrations (b), and conditionally weighted residuals versus population predicted concentrations (c) and time after dose (d). Broken lines are locally weighted least-squares regressions; solid lines represent the lines of identity. The concentrations are plotted on a logarithmic scale (base 10)
