Hi FreeSurfer experts,

Let's say I have two class variables:

Sex (female, male)
Dx (patient, control)

I see that the analysis results show the following:

Does the average thickness, accounting for Dx, diff between female and male?  
Red means: female > male
Does the average thickness, accounting for Sex, diff between patient and 
control?   Red means: patient > control
Is there a Sex-Dx interaction in the mean thickness?  Red means either (a) the 
female > male effect is stronger in patient (vs. control); or (b) the patient > 
control effect is stronger in female (vs. male)

Is my interpretation correct?

Thanks!
Daniel
