Notes: Data are shown as mean (SD) or number (%). Reported P-values from two-sample independent t-test for age and intracranial volume, Mann-Whitney U test for the non-normal variable education year, and chi-squared test for male proportion and handedness. ICV = intracranial volume; SD = standard deviation. *: Z value was reported for Mann-Whitney U test.
