Fig. 2. Prognostic power of several models for OS. The prognostic power was assessed based on (A) the AUC or (B) Harrell’s C-index determined with the IPSS-M, IPSS-R, AIPSS-MDS, EuroMDS, and MLL models. In panel B, the red line represents the risk encoded as categories using five risk categories (after merging the moderate-risk groups) for the IPSS-R and IPSS-M models and the quintiles using risk scores obtained from the original training set for the AIPSS-MDS model. The blue line represents a continuous score.
