  1. Partial correlation corrected for sex (df = 96). * P < .05 ** P < .01
  2. n varies from 104 to 107 depending on cognitive test (Table 1) and n = 99 for g
  3. WBV: whole brain volume, ICA: intracranial area, CCA: corpus callosum area, VV: ventricular volume, RFL: right frontal lobe volume, LFL: left frontal lobe volume, RTL: right temporal lobe volume, LTLV: left temporal lobe volume, RAHC: right amygdalo-hippocampal complex volume, LAHC: left amygdalo-hippocampal complex volume
  4. NART: National Adult Reading Test, RSPM: Raven's Standard Progressive Matrices, MHT: Moray House Test, VF: Verbal Fluency, LM: Logical Memory
  5. g: general cognitive factor (The first unrotated principal component of MHT, RSPM, VF and LM, accounting for 51.9% of the total variance: see text.)
  6. g corr for NART: estimate of cognitive change (see text)
