Radiogenomics of lower-grade gliomas: a radiomic signature as a biological surrogate for survival prediction
Figure 4. A nomogram for predicting overall survival of patients with LGGs (A), along with the assessment of model calibration in the training cohort (B) and validation cohort (C). After final model selection, radiomic signature, WHO grade, age, IDH status, and seizure were included in the nomogram. The line determines the number of points received for the value of each variable. The sum of these numbers is presented on the total axis, while the line drawn down to the survival axis determines the likelihood of a 1-, 2-, 3-, or 5-year survival rate. The calibration curve of the nomogram is also shown. Three colored lines (blue, red, and black) represent the performance of the nomogram, with a closer fit to the diagonal line representing a better estimation.
