Fig. 3: Adjusted trajectories of general cognitive function for the APOE haplotype groups.

This figure shows the adjusted trajectories of general cognitive function for three APOE groups (i.e. ɛ2 carriers, ɛ3 homozygotes and ɛ4 carriers) up to 20-years follow-up (n = 2559). T0-T20 represents time in years. The trajectories were adjusted for sex, age at baseline, and population stratification using the first two gPCs. In addition, we included time (0–20 years with 5-year intervals, i.e. five time points) into the model, and the interaction terms SNP*time and age at baseline*time.
