↵* Log (odds ratio).
↵† Total score.
+ve = positive; –ve = negative.
Score was obtained from odds ratio of clinicopathologic parameters significantly associated with ¹⁸F-FDG avidity from systematic literature review. Sixteen different combinations of parameters including GLUT1 status with combined score ranging from 0 to 8.05 were used.
