CSF Levels of Angiopoietin-2 Do Not Differ between Patients with CSF Fluid Leakage Syndrome and Controls

Table 2

Overview of cerebrospinal fluid (CSF) and angiopoietin-2 (Ang-2) parameters. Q: quotient, that is, CSF to serum ratio; alb.: albumin; Ig: immunoglobulin; C: control subjects; LS: subjects with CSF leakage; LP: lymphocytic pleocytosis; N: normal; ABC: artificial blood contamination; n.a.: not applicable; and n.d.: not done.
