  1. All parameters were estimated using non-linear mixed effect models. Here, r.s.e refers to the relative standard errors (%), σ a : standard deviation of additive residual error, and σ b : standard deviations of proportional residual error. For the meaning of the individual parameters see Fig. 2 and Materials and Methods.
