Fig 2. The weighted, multivariable-adjusted prevalence of open-angle glaucoma according to urinary albumin-to-creatinine ratio tertiles in nondiabetic subjects (A) and nondiabetic subjects with low-grade albuminuria within the normal range (B).

An analysis of covariance was performed with age, sex, serum triglyceride level, serum high-density lipoprotein cholesterol level, mean arterial pressure, education level, ever-smoker status, estimated glomerular filtration rate, and intraocular pressure as covariates.
