Figure 2. The Effect of ε4 Allele Status on the Rate of Change in Motor Function Varies with Age.

Figure 2

These figures are model generated of four hypothetical participants to illustrate the effect of ε4 allele status and age on motor function. Figure 2a shows the rate of motor decline in two participants without the ε4 allele: one age 80 years [solid line] and the other age 85 years [dashed line] at study baseline. Figure 2b shows the rate of motor decline in two participants of similar ages but who have at least one copy of the ε4 allele: age 80 years [solid line] and 85 years [dashed line] at study baseline.
