Dear Expert
So here is my PALM design (generated by GLM):
EV1: female patient
EV2: female control
EV3: male patient
EV4: male control
EV5: age of the female patient
EV6: age of the female control
EV7: age of the male patient
EV8: age of the male control
*Group Variable is set up differently for each group.
Group EV1 EV2 EV3 EV4 EV5 EV6 EV7 EV8
1 1 0 0 0 20 0 0 0
2 0 1 0 0 0 30 0 0
3 0 0 1 0 0 0 40 0
4 0 0 0 1 0 0 0 50
According to "Two Groups with continuous covariate interaction" in this fsl GLM webpage :
http://fsl.fmrib.ox.ac.uk/fsl/fslwiki/GLM#Two-Group_Difference_Adjusted_for_Covariate
I can only use this model to test the group x age interaction….and nothing else?
I did not find any significant group x age interaction, but I got interesting sex effect and group x sex interaction using this model…..can I still use these results???
Thanks so much!!!
