General Estimating Equations Comparing Outer Arterial Caliber Thickness in Eyes with and without Predominantly Peripheral Lesions

	Without Predominantly Peripheral Lesions	With Predominantly Peripheral Lesions	P Value*	Model 1†
Inner arteriolar caliber	103.17 ± 11.68	101.12 ± 14.90	0.466	—
Inner venular caliber	126.69 ± 14.39	127.44 ± 16.14	0.759	—
Outer arteriolar caliber	122.98 ± 29.50	109.66 ± 26.53	0.001	0.023
Outer venular caliber	117.22 ± 10.56	118.71 ± 15.48	0.440	—

— = no value.
