Figure 6. Construction and validation of nomograms based on COPS subunit expression. (A–C) Nomograms constructed to establish the prognostic efficacy of COPS subunits 5 (A), 7B (B), and 9 (C) for predicting 1-, 3-, and 5-year overall survival (OS). Calibration plots are also shown validating the efficiency of nomograms for OS prediction.
