^*Beta coefficient and 95% CIs represent the estimated effect of a covariate on macular thickness in micrometers. All continuous variables were scaled to internal z-scores centered on the study population mean prior to model fitting. Units for beta coefficients were µm/y/SD change for continuous variables or µm/y difference between outcomes for dichotomous variables.

^†P values were derived from linear regression analyses. Boldface indicates P < 0.05.
