Serum and cerebrospinal fluid Neudesin concentration and Neudesin Quotient as potential circulating biomarkers of a primary brain tumor

Table 3 Correlation coefficient results obtained in the whole brain tumors group (astrocytic plus meningeal tumor)

	CSF Neudesin	Neudesin Quotient	Na⁺	eGFR	Age
Serum Neudesin	R = 0.696; P < 0.001		R = 0.503; P = 0.006		R = 0.419; P = 0.026
CSF Neudesin		R = 0.747; P < 0.001		R = −0.517; P = 0.023
