Note:—AC3 indicates grade III astrocytoma.
↵a The areas under the receiver operating characteristic curves as a measure for diagnostic accuracy are reported.
↵b Two P values occur when two values (MK′ and MD) are tested at the same time.
↵c The variable contributes significantly to the regression model if the corresponding P value is <.05.
