^*Baseline for Stable Normal group is study entry (assessment 1). Baseline for MCI groups is the assessment at which the participant was first classified as MCI (CDR=0.5)

^†For example, a one-unit change in the composite attention domain score multiplied the risk of reversion by 0.657, of stable MCI by 0.563, and of progression by 0.375, compared to remaining stably normal.
