Generalized estimating equation (GEE), which adjusts for the correlation between eyes, was employed in the analyses. The Wald Chi-Square P-value is reported and means are given as least square mean ± se. All models are adjusted for race, gender, and age group (categorized by decades: 20’s, 30’s, 40’s,50’s, and 60+).
