Figure 2. Nomogram predicting 1-, 3- and 5-year cancer specific survival for pediatric brainstem glioma patients.
The C-index of the nomogram thus constructed was 0.75, which demonstrates a relatively great predictive probability. Calibration plots of the nomogram (Figure 3) demonstrated an agreement between predicted CSS and the actual observations. The decision curve analysis evaluated 1,3 and 5-year CSS of children stem glioma patients, which showed all models had a better net benefit compared to the “treat all” strategy (Figure 4).
