Coefficient of repeatability of QAF8 measurements.
| Disease stage | Coefficient of Repeatability [a.u.] | ||
|---|---|---|---|
| Intra-day | Inter day | Inter-eye | |
| All eyes | 55.31 | 100.58 | 113.34 |
| Healthy | 68.34 | 127.81 | 126.27 |
| Early | 81.06 | 111.15 | 173.11 |
| Intermediate | 45.63 | 77.96 | 110.92 |
| Late (geographic atrophy and neovascular pooled) | 45.38 | 92.04 | 90.14 |
Listed are the coefficient of repeatability (CoR) 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 CoR for all eyes, 2 for healthy only, 3 for early-only, 4 for intermediate-only and 5 for late-AMD (both geographic atrophy and neovascular pooled) only.
