Regression analysis comparing several variables between Asian Americans and Caucasian Americans, controlling for age and sex. Axial length was included in the adjustment for those variables marked with an asterisk (∗). SE: standard error. Measurements were taken with Fourier-domain optical coherence tomography.

Variable	Effect size (Asians as reference) ± SE	P value
Spherical equivalent (D)	−2.95 ± 0.64	<0.001
Axial length (mm)	−1.03 ± 0.38	0.007
Intraocular pressure (mmHg)	−2.74 ± 0.62	<0.001
Retinal nerve fiber layer thickness (μm)∗	−3.60 ± 2.73	0.19
Cup to disc area ratio∗	−0.12 ± 0.046	0.012
Central corneal thickness (μm)	−1.66 ± 8.20	0.84
