Hi,
Does anyone have any references they can recommend about the order of treatments
given to different groups during a cross-over study?
I'm particularly interested in the effect of simple cycling of treatments (e.g.
group 1 receives order A B C D, group 2 receives order D A B C, group 3 receives
order C D A B, group 4 receives order B C D A) compared to non-cyclic ordering
(e.g. group 1 recieves order A D C B, group 2 receives order B C D A, group 3
receives order C A B D , group 4 receives order D B A C) so that no one
treatment ever follows another treatment in the same order.
I'll summarise replys to the list.
Thanks,
Joy
