To implement the summary measure in a time-to-event equation, it must
be applied to the reference equation because the measure itself does not
carry sufcient information to derive the intervention quantile function sep-
arately. This involves converting the summary measure into a form that can
be applied to the reference quantile function. The required steps depend on
the specics of the reference equation (see Chapter 6).
For DES that check at xed time steps to determine whether an event hap-
pened, summary information regarding risk or proportion achieving a result
can be applied directly in the simulation by using it to adjust ...
