Accordingly, VCAM‐1 has a moderating role in diabetes‐related cognitive functions at low (B = −0.356, p = 0.0310 for 49.34 ng/mL), medium (B = −0.355, p = 0.003 for 69.28 ng/mL), and high (B = −0.354, p = 0.041 for 89.22 ng/mL) levels of VCAM‐1 values (p < 0.05). This evidence concerns the gene VCAM1 and diabetes mellitus.
