Multiple linear regression model showing the relationship between age, sex, BMI, retinal thickness, maxOD, and meanOD.

Variables	MaxOD		MeanOD
	Age	0.408	<0.001	0.591	<0.001
Sex	0.167	0.089	0.172	0.066
BMI	−0.188	0.042	−0.193	0.028
smoking	0.030	0.763	0.047	0.622
GCC	0.454	<0.001	0.316	0.001
OR	0.029	0.763	0.010	0.909

BMI: body mass index.
GCC: ganglion cell complex.
OR: outer retinal thickness (CRT minus GCC).
