Evolution of the amount of borrowing value, that is, $\alpha ={\alpha }_0(1-\gamma )$, at the end of the trial, for models AP_SOC2, AP_S and AP_MIX(05) in all five scenarios. On the x-axis, scenarios (SC) are represented by their difference in the probability of toxicity at dose 3 with respect to the historical data (assumed to be 0.20). On the right, more toxic scenarios than SC3 are plotted.
