S i,0 can also help to quantify the difference between RT-qPCR and pretreatment-RTqPCR (i = 2) or the cultural titration method (i = 3). GInaFiT also returns the standard error values

of the estimated parameter. These standard errors were used to construct asymptotic learn more parameter confidence intervals. When no inactivation was observed, k max and S i,res were presented as zero with no confidence intervals, and the considered experiments were simply represented with S i,0. When no quantification was possible after 1 minute of treatment, corresponding to very fast inactivation, the limit of quantification (LOQ) value was used to set a value for k max and S i,res. k max was set at its minimum possible value, ln(10)·LOQ and S i,res were set to their maximum possible value, i.e. LOQ. No confidence intervals were given for either parameter.
