Figure 2. Cumulative Probability of Diabetic Retinopathy Worsening Among Eyes Treated with Ranibizumab for Diabetic Macular Edema.
Cumulative probability of worsening of diabetic retinopathy by baseline retinopathy subgroup. There was a difference in the rate of worsening between the NPDR and PDR group [P = .01]. There was no difference in the rate of worsening between the 1st, 2nd, 3rd, 4th, and 5th years within each DR group (P > .05). NPDR=non-proliferative diabetic retinopathy, PDR=proliferative diabetic retinopathy.
