nearly statistically significantp = 0.05
This difference was nearly statistically significant ( p = 0.05), and this result was comparable to those in a previous study that revealed a lower rate of concurrent autoimmune diseases in MOGAD patients compared with seropositive AQP4-IgG patients. 13 Clinical Characteristics at ON Presentation In our study, the incidence of bilateral simultaneous ON was observed strikingly more frequently in the MOG-IgG + ON group compared with the AQP4-IgG + ON group (80% vs 8%, MOG-IgG + ON vs AQP4-IgG + ON patients, respectively; p < 0.001).
