Quantification of signalling proteins. Quantification of signalling proteins: IL-6 in CSF (A) and serum (B), VEGF in CSF (C) and serum (D), TGF-β₁ in CSF (E) and serum (F). Boxes contain values from 1st to 3rd quartile, lines inside boxes indicate median values, endpoints of vertical lines display 5th–95^th percentile and · represent the outliers. Asterisks indicate statistically significant differences from the disease category ‘SRMA untreated’ (* P < 0.05; ** P < 0.01; *** P < 0.005). IL-6: interleukin-6; VEGF: vascular endothelial grow factor; TGF-β₁: Transforming growth factor beta 1. CSF cerebrospinal fluid; CNS: central nervous system; SRMA: steroid-responsive meningitis-arteritis; ME: other inflammatory CNS diseases; CNS-Mix: miscellaneous non-inflammatory CNS diseases; Syst Inflam: systemic inflammatory diseases; IE: idiopathic epilepsy.
