Fig. 4From: A prediction model for worsening diabetic retinopathy after panretinal photocoagulationPlotting deciles of the predicted probability of DR-worsening against the observed probability for the model: A, C the training cohort; B, D the validation cohort. The x-axis is the predicted risk and the y-axis is the actual risk. The blue solid lines indicate the performance of the model, and a closer fit to the diagonal dotted lines indicates a better predictionBack to article page
