Mean per cent change in tumor diameter as a function of the time after the beginning of treatment for virtual patients. Simulations were grouped according to RECIST criteria; progressive disease (PD; x>20%; red), stable disease (SD; −30%≤x ≤ 20%; yellow), partial response (PR; x < −30%; cyan), and complete response (CR; x = −100%; green). Shaded regions correspond to the 95% CI of the simulations in the corresponding RECIST category. RECIST, Response Evaluation Criteria in Solid Tumors.
