Fig. 3From: Comparison of digital image analysis and visual scoring of KI-67 in prostate cancer prognosis after prostatectomyPrediction accuracy of Cox regression model (outcome: death by prostate cancer). The graphs (a) and (c) represent the ROC curve at the 12.5th year after radical prostatectomy for the non-adjusted and adjusted model, respectively. The graphs (b) and (d) depict the C-index for non-adjusted and adjusted models, respectively assessed on 12.5 years after radial prostatectomy. The red curve represents the chance, while the black, blue and green line represents the measures obtained with DIA, H-score and the visual scoring, respectively.
