IL36RN and Guillain-Barre syndrome: The results showed that CSF IL-36α and IL-36γ levels in GBS were positively correlated with GDSs (r = 0.627, P < .01, Fig. 5a; r = 0.639, P < .01, Fig. 5g, respectively), while CSF IL-36Ra levels were negatively correlated with GDSs (r = −0.650, P < .01, Fig. 5j).
