a The numbers refer to baseline data, with the exception of MMSE_c, CDR_c, and LM-del_c, which refer to change across 2 years (baseline score subtracted from score at 2-year follow-up). MMSE and LM-del change scores were available for 36 NC, 51 MCI, and 25 AD subjects. CDR-SB change scores were available for 34 NC, 49 MCI, and 25 AD.
