Hello, I'm trying to analyse some data but I'm not sure if I'm using the correct test - I'd be very grateful for some advice from someone who does know !
I have 5 subjects. In a cross-over design each subject was exposed to each of the 4 treatments (test meals using 4 different types of bread). I have data on insulin response for 6 different time points following each meal. My main question is does the insulin response differ at any time point between the 4 treatments (breads).
I've been using a repeated measure ANOVA in Jmp (Fit model - insulin at each of the 6 time points in Y - Subject and Bread in construct model effects. Then 'time' in specification of repeated measures).
What I'm not sure about is does this take account of the cross-over design and that each meal is repeated in each subject - ie. it's not 20 seperate test meals in 20 subjects - it's 20 test meals in 5 subjects.
If this is the correct test, which p-value answer my question ?
