a. fD(t) is the traditional DALY formulation that is, stillbirths are not incorporated, and ALP is instantaneous.
b. fDSB(t) is the traditional DALY formulation extended to give equal weight to stillbirths as to deaths at age 0, that is, it leads to DALYsSB(3,0,1).
c. f2(t) is the ALP function used to generate the DALYSB (3,0,.54) GBD estimates reported in table 6B.8. These are DALYs that incorporate stillbirth and gradual ALP.
