Hi
I want to conduct a clinical trial, which includes comparing 3 different treatments.
I want to use a 4 groups experimental time series design, which involve 3 treatments and a control group. I will assigns subjects to these 4 groups randomly.
R O O O X1 O O O
R O O O X2 O O O
R O O O X3 O O O
R O O O X4 O O O
is this okay?
how can I analyses the results?
and can you give some resources regarding these kinds of research design?
Thanks
To compare among those 4 groups, you need to do MANOVA analysis. This will compare between groups differences.
To test changes over time, you need to do Repeated Measure ANOVA. This will give you within gourps changes.
yes, you can use any one approach as:
1-Multivaruiate analysis (MANOVA) ( time is a factor )
2-split-plot design in time (time is subplot factor)
3- Repeated analysis to see the effect of change in time
you can read some papers about this I published in research gate
With Best Regards
