Here, we consider central nervous system tumors in a broader sense and cover all tumor types in the central nervous system including meningiomas, gliomas, and spinal cord tumors. The wildcard character (*) that could be substituted for any other characters and allows variable endings of keywords was used. For example, “glioma*” would also return the terms of “glioma” and “gliomas”. The wildcard character of NEAR/1 was used to search for two words, in an arbitrary order, separated by a maximum of one term (e.g., CNS NEAR/1 tumor* would have identified “CNS tumor*” and “CNS malignant tumor*”).
