Fig.Ā 1From: A new M23-based ELISA assay for anti-aquaporin 4 autoantibodies: diagnostic accuracy and clinical correlationDistribution of anti-AQP4 autoantibody levels, expressed in Units/mL, in patients with neuromyelitis optica (NMO), longitudinally extensive transverse myelitis (LETM), optic neuritis (ON), myelitis and controls, including patients with multiple sclerosis (MS) and healthy subjects (HS). Kruskal Wallis test, pāā<ā0.0001; the median level of anti-AQP4 Ab was statistically higher in patients with NMO than in LETM and ON patients (MannāWhitney Unpaired U-test, pāā=ā0.0006 and pāā<ā0.0001, respectively)Back to article page
