Correlations between choroid measurements at baseline and the annual square root enlargement rates of geographic atrophy in different regions

Choroidal Parameters	Regions of Interest	Mean (SD)	Pearson r	P value
MCT (Unit: μm)	Inside of GA	155.75 (88.33)	−0.21	0.22
	Outside of GA	151.83 (77.51)	−0.24	0.15
	Total scan area	151.42 (77.86)	−0.23	0.16
CVI	Inside of GA	0.57 (0.04)	−0.35	0.03
	Outside of GA	0.59 (0.03)	−0.29	0.07
	Total scan area	0.59 (0.03)	−0.30	0.07

MCT: mean choroid thickness, unit: μm; CVI: choroidal vasculature index; GA: geographic atrophy; SD: standard deviation
