%description
Estimate the causal effect of sustained treatment strategies on overall
survival in clinical trials with possible treatment crossover and switch
to subsequent therapy. Simulate faithful longitudinal clinical trials data
with survival endpoints and multi-way treatment switches allowing for
time-dependent prognostic factors. For more on methodological background,
please see: Keogh and colleagues (2021) <doi:10.1002/bimj.202000040> and
Suarez and colleagues (2008) <doi:10.1016/j.jclinepi.2007.11.007>.
