Fig 5. Estimated probability and observed glioma (GBM) curve based on logistic regression analysis. Y-axis represents the estimated probability that a tumor is not a GBM, and the x-axis represents the average percentage of signal intensity recovery (celAvg_Recov) within the contrast-enhancing lesion of the tumor. This curve shows that when a cutoff of 
66% signal intensity recovery is used, there is 100% specificity to correctly predict that a tumor is not a GBM with a sensitivity of 69%. The small circle (
) represents GBM, and the plus sign (+) represents metastasis. The shaded area is the confidence interval.
