Furthermore, the 13 AD‐related genes were significantly correlated with the T‐map of the difference between the A‐CI and N‐CI groups (p < 0.05, Bonferroni corrected), excluding Amyloid Beta (A4) Precursor Protein (APP), Beta‐Site APP‐Cleaving Enzyme 2 (BACE2), and Plasminogen activator urinary (PLAU) (p = 0.04, Figure 6B). Here, APP is linked to Alzheimer disease.
