CRAE denotes central retinal arteriole equivalent; CRVE, central retinal vein equivalent.

^*Age, sex, race, and CRVE (continuous) adjusted.

^†Age, sex, race, and CRAE (continuous) adjusted.

^‡Adjusted means and proportions and according to quintiles, and p-values for overall difference, were calculated by a general linear model.
