APOE and Parkinson disease: Given the strong effect from APOE in AD and DLB, we have performed the same analysis excluding this locus in these 2 cohorts and obtained a correlation score for AD/DLB_NO_APOE (0.332 ± 0.106) that is not statistically different from the PD/DLB correlation (0.362 ± 0.107) (p-value = 0.761, using the same test as mentioned previously).
