  1. Stepwise multiple linear regression analyses were performed separately for the total score and each sub-score in the four domains. Age, sex, midbrain AP/cranial AP diameter, pons AP/cranial AP diameter, pons transverse/cranial AP diameter, cerebellar height/cranial AP diameter, and cerebellar volume/cranial AP diameter were used as dependent variables
  2. AP anteroposterior, SD standard deviation
