Hi Zheng
yes, I see. Maybe the effect is smaller than you have the power to see, or
there is no effect? You would need to give us more details for us to help.
Are you correcting for eTIV? What measure are you comparing?
cheers

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 this result.
Can you understand me this time?
Thanks,
Zheng
