Hi Greve,
Thanks for your help. I have 28 females and 26 males in one group. If it is
necessary to take gender and eTIV as a covariate, I don't know how to take
them as covariate in SPSS. Subcortical volume can be divided by eTIV, but for
gender, I don't know how to do. And the mean age of female and male don't have
statistical significance (p=0.362).In this case, is it possible to ignore the
effect of gender?
Sincerely,
Zheng
