Visits occurring between 315 and 468 days (between 45 and 67 weeks) from randomization were included as 56-week visits. When more than 1 visit occurred in this window, data from the visit closest to the 56-week target date were used.

Adjusted for baseline visual acuity, number of planned panretinal photocoagulation (PRP) sittings, and correlation between 2 study eyes. Confidence intervals (CI) are adjusted for multiple comparisons.
