Selection of lncRNAs That Influence the Prognosis of Osteosarcoma Based on Copy Number Variation Data

Figure 5

Nomograms based on the independent prognostic factors in patients with osteosarcoma: (a) univariate Cox analysis of overall survival-related variables; (b) multivariate Cox analysis of overall survival-related variables; (c) nomogram to predict 1-, 3-, and 5-year overall survival probability by integrating the risk score and clinicopathologic risk factors; (d) plot depicting the calibration of the nomogram in terms of the agreement between predicted and observed outcomes. Nomogram performance is shown by the plot relative to the dotted line, which represents perfect prediction. (e) Proportional hazard assumption revealed that the nomogram had good predictive efficiency.
