Results of the logistic regression differentiating high-grade from low-grade gliomas.

The area under the curve (AUC) as an accuracy measure for discrimination between high-grade and low-grade gliomas. The AUC is calculated for the three parameters and their combinations in the enhancing tumor, the peri-focal edema, and a combined region of enhancing tumor & peri-focal edema. A p-value ≦ 0.05 (marked with *) allows the conclusion that the predictor has enough strength to distinguish between the two groups.Results of the logistic regression differentiating high-grade from low-grade gliomas.
