The meanings of symbols representing subpopulations are given in Table 1, and the meanings of symbols representing parameters (including derived parameters) are given in Table 2. Note that only re-selections resulting in transition to the other risk group are shown; loops depicting re-selections that place the individual in the same risk group (and therefore same compartment) they were in prior to re-selection are not included.
