Hi all,
For my fMRI study I have 30 individuals per group (two groups).
Both groups were randomized to placebo or treatment condition (so 15 individuals per condition).
I compared both groups (irrespective of condition) at baseline and also investigated the treatment effect (follow-up)
Would this be a sufficient sample size? I have a reviewer who is wondering this....
Any suggestions or tips are welcome!
Thanks!
Heidi
