Intermediate decline with extra random effect
For the scenarios with no treatment effect, the Type I errors were close to 5% (Tables A6.1.1 and A6.1.3, There were some differences in the mean treatment effect from the target treatment effect when using the random slopes model in the scenarios with a treatment effect proportional to control group arm change, although somewhat less than for the other non-linear trajectories (Tables A6.3.1 and A6.3.3,
