Discriminating nomogram. A Nomogram makes accessible for clinicians to identify the epileptogenic tubers according to quantitative indices of.18F-FDG PET images. Gray density plots describe the distribution of epileptogenic tubers in quantitative indices and total points. *P < 0.05, **P < 0.01. B Calibration curve for the nomogram to identify epileptogenic tubers. X-axis represents the nomogram-identification probability of epileptogenic tubers, and Y-axis represents the actual proportion of epileptogenic tubers. The diagonal dotted line indicates the best prediction by an ideal model. The apparent line represents the uncorrected performance of the nomogram, and the solid line shows the bias-corrected performance. 1000 bootstrap repetitions; mean absolute error = 0.046; n = 235
