Specification of the persistence properties of the grade 1 value of the Myelotoxicity (bone marrow toxicity) parameter in the context of the PAZ protocol, as used in the temporal-abstraction knowledge-acquisition tool. The expert has selected the Grade_1 layer of the (conceptually) three-dimensional persistence table, and specifies, in the bottom-right subwindow, a two-dimensional table that defines the maximal gap that allows concatenation of two intervals of grade 1 bone marrow toxicity, as a function of the duration (Interval length) of the interval before the gap and the duration of the interval after the gap. The lengths of the two intervals are the indices of the two-dimensional table; the value of the parameter (in this case, Grade_1) is the layer index for the three-dimensional table.
