Thanks for your reply. Yes, I meant the difference between the chi-sqare values (from group*time, generated automatically) and the z values from that contrast. So if they're essentially the same, can I report either one?
Also, a question about reporting the main effects: My goal was to find out if there is a group*time effect. Do I have to report the main effects Time and Group, too?
