case we expect that Exp(a) = Exp(b) (or approximate) ie the ratio of two odds estimates the ratio of tow hazards ie the logistic model and the Cox model give the same (or approximately) results ?? Thank you in advance. |===| | Hassane ABIDI (PhD

atement "model Y1-Y7 = treatment /nouni" by "model model Y1-Y7 = /nouni" NB. I think, that you must begin by plotting Y versus time by treatment to look if you can expect a plateau from your data. Good luck. Hassane |=========
