Meta‐analysis of foveal avascular zone (FAZ) measurements (mm 2 ) for Alzheimer's disease (AD), mild cognitive impairment (MCI), and preclinical AD (preAD) participants versus controls (C) and AD versus MCI. Mean and standard deviation (SD) are included, with 95% confidence intervals (CIs), heterogeneity scores, and overall effect in an inverse variance (IV) random effects model. The green square size represents the weight attributed to each study based on relative sample size. N.B. Results from van de Kreeke et al. are unadjusted and were obtained through personal correspondence with authors.
