Virological rebound after 1 weeks. Virological rebound at 1 week after therapy interruption for different starting time points of HAART (t
). The red dots represent the results of thousands simulations and the fitting line is given by the Richards' curve in equation 1. Standard deviation is about 0.1 log10(copies/ml) for all points. Inset plot is a zoom for t
< 30 days. Parameters of the fitting curve are: a = 1.52, k = 3.79, d = 0.12, and = 23.50.
