I am measuring test performance at 10 different timepoints, before and after drug application.
So far I ran two-way repeated measures ANOVA and determined there is a significant timepoint, drug, and timepoint*drug effect.
We are particularly interested whether the test performance is different between the control and drug group at timepoints 1, 5 and 10.
I have been considering testing these three timepoints separately using paired t-test for each. I was wondering if that is an appropriate approach? Is it necessary to control for multiple comparisons? Which tests would be most suitable?
