Hello,
I came across a set of data comparing 2 medical approaches in terms of several continuous variables (Primary objective is compare A to B).

Medical approaches were applied in 5 different pattern (I cannot understand the reason of that why these patterns were used);
A-B-A-B
A-B-B-A
A-B-B-B
B-A-A-B
B-A-B-A

What's your opinion about study design?
and any recommendation for the analysis

Thanks
MB
