Hi Bruce,
I am sorry for this situation.
In the first way, there was an statistical difference in left hippocampus,
but no difference in right hippocampus. In the second way, there was both no
statistical difference in left or right hippocampus. I don't know what causes

Hi Zheng
yes, I see. Maybe the effect is smaller than you have the power to see, or

I have 54 subjects, aged from 21 to 71 and only one group. I want to
compare the change of hippocampus volume with age. The results before and after

Thanks again.

Hi Zheng
I would scatter plot age vs. volume, coloring men and women differently
(or different symbols) with and without eTIV correction to get an idea of
what is going on
