Text: Statistically significant risk factors for GA in the multivariate model for all eyes were older age (RR, 6. 39 [95 % CI, 1. 64-24. 9] for > 79 years vs. 50-59 years), greater retinal area covered by drusen (RR, 5. 10 [95 % CI, 2. 57-10. 1] for > or = 25 % vs. < 10 %), retinal pigment epithelium (RPE) depigmentation (RR, 2. 64 [95 % CI, 1. 26-5. 53), and focal hyperpigmentation (RR, 10. 4 [95 % CI, 4. 51-24. 0] for > or = 250 microm vs. none).
