Fig. 8

5-year trials with non-proportional treatment effects and smaller residual error variance. Left-hand panel: mean treatment effect at 5 years, converted from differences in slopes between the treatment groups for the random slopes and linear trajectories, free covariances models. Right-hand panel: power. Ranges are \(\pm 1.96\) times the Monte Carlo standard error
