Power of tests of equal survival function under increasing lag until effect DGM. Effect of non-constant event rates on the power of seven tests of equal survival function. The power of the z-test for the HR treatment effect from the Cox PH model is included in the panel as a comparator. Lag period lengths investigated were tlag = 0, 1, 3 and 10 months within the maximum follow-up time t = 50, with the setting tlag = 0 representing PH
