  1. For favipiravir, a Hill coefficient of nF = 1 and nF = 3.544 was chosen.
  2. The mean of the estimated parameters with their respective relative standard errors (in %) are shown. For the analysis, we expressed the dose-dependent- efficacies as: \(\varepsilon ={{\rm{D}}}_{{\rm{F}}}^{{{\rm{n}}}_{{\rm{F}}}}/({{\rm{D}}}_{{\rm{F}}}^{{{\rm{n}}}_{{\rm{F}}}}{+(\mathrm{ED}}_{{\rm{50}}}^{{\rm{F}}}{)}^{{{\rm{n}}}_{{\rm{F}}}})\) for favipiravir, and \(\gamma ={{\rm{D}}}_{{\rm{R}}}^{{{\rm{n}}}_{{\rm{R}}}}/({{\rm{D}}}_{{\rm{R}}}^{{{\rm{n}}}_{{\rm{R}}}}+{{(\mathrm{ED}}_{{\rm{50}}}^{{\rm{R}}})}^{{{\rm{n}}}_{{\rm{R}}}})\) for ribavirin. This sensitivity analysis was carried out with fixed T 0 = 106 cells/ml and V 0 = 10 FFU/ml.
