  • Continuous data are mean (standard deviation). Note that the total number differs from the complete MCI cohort. For the SMCI versus PMCI comparisons we only included SMCI subjects with at least 2 years of follow‐up. P‐values tested by Fisher's exact test and Mann–Whitney U‐test. SMCI, stable mild cognitive impairment; PMCI, progressive mild cognitive impairment.
