We adopt the view that the effects of time are linear. So, we have deaths acorss two groups (0 = control, 1 = treatment) at three time points (0 = baseline, 1 = 1 year in, 2 = 2 years in). We pre-specify a linear predictor relating group …

And if the interaction term is statistically significant (associated with a p-value < 0.05), then: β 3 can be interpreted as the increase in effectiveness of X 1 for each 1 unit increase in X 2 (and ...
