Medulla oblongata and Cervical Spinal Cord MRI characteristics of NMOSD attacks, comparing attack requiring OTI versus attacks not requiring OTI. OTI orotracheal intubation; percentages: number of attacks with radiological anomalies (new T2 lesion, gadolinium-enhancing lesion, increase volume)/number of attacks with available MRI, among OTI and non-OTI-attacks. P-value is estimated with binomial generalized linear mixed model, with a random intercept for patient ID. Due to separation issues, p-value has not been estimated for some variables
