From: Serum tau protein elevation in migraine: a cross-sectional case–control study
Blood serum concentrations of total-tau, NfL, GFAP, and UCH-L1 in pg/mL for patients with EM and CM and healthy controls. Legend: t-tau = total tau; NfL = neurofilament-light; GFAP = glial fibrillary acidic protein; UCH-L1 = ubiquitin C-terminal hydrolase L1; HCs = healthy controls; EM = episodic migraine; CM = chronic migraine. a p-value for between-group difference as estimated with the Independent-Samples Kruskal–Wallis Test for continuous variables, corrected with the Bonferroni correction for multiple comparisons. P-values < 0.05 are depicted in bold
