Nonvascular retinal imaging markers of preclinical Alzheimer's disease.

Although the effect size difference between these two groups is large (Cohen's d = 0.80), this difference did not reach statistical significance due to small sample size for the Aβ− group (N = 10); and (3) IPL volume is associated with increased total surface area of retinal inclusion bodies.

Finally, it was only the IPL that showed a robust increase in thickness for the Aβ+ group relative to the Aβ− group, although this difference failed to reach statistical significance due to a small sample size in the Aβ− group (N = 10).
