Dear SPMer's,
We have a data set consisting of 6 depressed subjects and 6 control
subjects with 2 baseline scans and 2 scans following a pharmacological
challenge. We have Hamilton Rating Scale for Depression scores (HRSD) for
each subject. Is it worthwhile to do a covariate analysis with the HRSD
score for the two groups given the small sample size of each group?
Thanks,
Cindy
