Final prediction models with integration of all imaging parameters at all time points (Model Combo) and with imaging parameters that were obtained at TP1 and TP3 (Model Combo13). Whether a patient has achieved ypT0-1N0 response is predicted by multiplying the weight of the retained parameters by their values obtained in an individual patient.
