Univariable multilevel linear regression analysis for whole DCP.

Variable	coefficient	95% CI	value
Fovea CRT	−0.146	−0.181	0.186
Parafovea CRT	0.066	−0.054	0.101
Whole DCP/SCP ratio	0.784	44.826–57.887	<0.001
Fovea DCP/SCP ratio	0.164	0.019–0.068	<0.001
Parafovea DCP/SCP ratio	−0.243	−48.862 to −17.057	<0.001
Macular^a	0.909	7.55–10.58	<0.001

CI means confidence interval, CRT means central retinal thickness, value <0.05 was considered significant, DCP means deep capillary plexuses, and SCP means superficial capillary plexuses, a macular intact was considered as the reference term.
