Mixed-model regression of geographic atrophy area according to the presence or absence of subsequent exudative neovascular age-related macular degeneration.

	Number of eyes (participants)	Change per year in square root of GA area			Change per year in GA area
	Number of eyes (participants)	Estimate (mm)	95% CI (mm)	P^*	Estimate (mm)	95% CI (mm)	P^*
Incident GA without subsequent exudative NV-AMD	684 (561)	0.29	0.27–0.30	0.037	1.13	1.05–1.20	0.004
Incident GA with subsequent exudative NV-AMD	73 (73)	0.20	0.12–0.28	0.037	0.62	0.29–0.96	0.004
Prevalent GA without subsequent exudative NV-AMD	393 (321)	0.28	0.26–0.29	0.37	1.41	1.31–1.51	0.87
Prevalent GA with subsequent exudative NV-AMD	63 (59)	0.31	0.24–0.37	0.37	1.38	1.10–1.75	0.87

Abbreviations: CI = confidence interval; GA = geographic atrophy; NV-AMD = neovascular age-related macular degeneration.

P values for interaction between presence/absence of subsequent exudative neovascular age-related macular degeneration and years from first appearance of geographic atrophy.
