- Values are presented as mean (SD)
- p values were derived from ANOVAs for continuous measures and from chi-squared tests for categorical measures
- MMSE Mini-Mental State Examination, ADAS13 Alzheimer’s disease assessment scale, cognitive subscale, ADNI-MEM episodic memory composite score
- Mean values significantly (p < 0.05, post hoc tests) different from aCN, bMCI, and cDementia
