Rates of Decline in Alzheimer Disease Decrease with Age
Figure 5
Data points show percentage, for successive 3-year age groups, of participants who progressed to dementia within 36-months from baseline.
Linear fit to data has slope = −0.94 [%/year] (standard error = 0.11, p = 0.00016). Ratios give the number of those who developed dementia to the total number of MCI participants, for each 3-year age window.
