Table 2.
Geographic atrophy enlargement rates according to reticular pseudodrusen status.
| RPD status* | Estimate† (mm/year) |
95% CI (mm/year) |
P‡ |
|---|---|---|---|
| RPD absence (n=657 eyes) |
0.269 | 0.258–0.281 | <0.0001 |
| RPD presence (n=114 eyes) |
0.388 | 0.347–0.430 |
Abbreviations: CI=confidence interval; RPD=reticular pseudodrusen
*
RPD status defined at study baseline for eyes with prevalent geographic atrophy (GA) and at first GA appearance for eyes with incident GA
†
Mixed-model, repeated-measures regression with the square root of GA area as the dependent variable
‡
P value for interaction between RPD status and years
