Association of sGFAP and sNfL with age. Association of sGFAP a and sNfL b with age of patients with AQP4-IgG⁺ NMOSD (n = 33), MOG-IgG⁺ patients (n = 16), and healthy controls (n = 38). Results of linear models using log-transformed values of sGFAP and sNfL are shown below the plots. AQP4-IgG aquaporin-4 immunoglobulin G, β regression coefficient, CI confidence interval, effect size standardized effect size, MOG-IgG myelin oligodendrocyte protein immunoglobulin G, NMOSD neuromyelitis optica spectrum disorder, sGFAP serum glial fibrillary acidic protein, sNfL serum neurofilament light chain protein
