Mixed-model regression of geographic atrophy area according to the presence or absence of subsequent exudative neovascular age-related macular degeneration, in the incident geographic atrophy cohort, according to different follow-up periods.

	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^*

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