Hello Experts,

I am analyzing cortical thickness of two groups (APOE 4carries vs. noncarriers) 
in freesurfer with age as a co-variate.
I am uncertain about the statistical differences behind:
1)Does the correlation between thickness and age accounting for APOE, differ 
from 0?

    in contrast to:

2)Does the thickness-age correlation differ between 1 and 0?

I get significant results after FDR correction for the first but not for the 
second analysis. 

thank you for your help,
catherine
