Intraclass correlation coefficient of QAF8 measurements.

Disease stage	Intraclass correlation coefficient (ICC [95% CI])
	Intra-day	Inter-day
All eyes	0.95 [0.93–0.96]	0.79 [0.72–0.85]
Healthy	0.91 [0.86–0.95]	0.70 [0.54–0.83]
Early AMD	0.96 [0.48–1.00]	N/A
Intermediate AMD	0.95 [0.92–0.97]	0.84 [0.73–0.91]
Late AMD (geographic atrophy and neovascular pooled)	0.94 [0.90–0.97]	0.64 [0.42–0.82]

Listed are the intraclass correlation coefficient (ICC) of QAF8 measurements for two clinically relevant scenarios: “Intra-day” were duplicate images acquired on the same day: “Inter-day” were images acquired approximately 2 weeks apart. Row: 1 shows ICC for all eyes, 2 for healthy only, 3 for early-only, 4 for intermediate-only and 5 for late-AMD (both GA and neovascular pooled) only.
