 n_{test} represents the number of data considered for evaluation of the model. The time points t_{f} and t_{s} represent, respectively, the time considered for model training and for calculation of the absorbed dose using the MLR equation at t_{f}. The coefficients of determination \({r}_{\mathrm{test}}^{2}\) are also shown
