We used descriptive analyses for the demographic data related to the ethnic cohorts. Nonparametric Wilcoxon rank-sum tests were used to compare cohorts regarding LP, RLP, CCT, LT, and AL. We used linear mixed-effect models to compare differences in LP and RLP between ethnic cohorts while accounting for each eye as a separate entity to maximize the effect of randomization plus including both eyes for analysis. Two-tailed P value <0.05 was deemed statistically significant. All statistical analyses were conducted using Stata version 14.0 (Stata Corp LLP, College Station, TX, USA).
