Fig. 3From: A prediction model for worsening diabetic retinopathy after panretinal photocoagulationBoxplots of predicted probabilities in the two models: A the model with training cohort (Slope = 0.28); B the model with validation cohort (Slope = 0.29). The discrimination slope was defined as the difference between the mean predicted probability with DR-worsening (1) and non-DR-worsening (0)Back to article page
