Scatter plots illustrating Spearman’s correlations between (A) OU superficial vessel density and PANSS positive subscore, (B) OU deep vessel diameter index and PANSS total score, (C) OU deep vessel diameter index and PANSS negative subscore, (D) OU deep vessel density and BACS composite score, (E) OU deep skeletonized vessel density and BACS composite score, and (F) OU deep fractal dimension and BACS composite score. Retinal vascular measures were adjusted for age, sex, race, visual acuity, body mass index, OCT-A scanner, and image QC. Clinical measures were adjusted for age, sex, and race, but BACS composite scores were adjusted for only race. OU = oculus uterque; PANSS = Positive and Negative Syndrome Scale; BACS = Brief Assessment of Cognition in Schizophrenia; OCT-A = optical coherence tomography angiography.
