↵* Comparing ND with RR patients using Cochran–Armitage Trend test.
Data for ND (anaplastic astrocytoma, primitive neuroectodermal tumor/pineoblastoma, and other categories) and for RR (primitive neuroectodermal tumor/pineoblastoma, and other categories) in Table 1 have not been included because of small sample size. Column categories are based on subjective grading of intensity of 18F-FDG uptake.
