However, in the adult group (\u226518 years old), the most common symptoms were blurred vision (45.7%), paralysis (37.0%), and paresthesia (32.6%).

The most frequent clinical phenotype in the pediatric group was acute disseminated encephalomyelitis (ADEM; 41.7%), whereas optic neuritis (ON; 32.6%) and transverse myelitis (TM; 26.1%) were more common in the adult group.

In both pediatric and adult patients, cortical\/subcortical and brainstem lesions were the most common lesions on cranial magnetic resonance imaging (MRI), whereas, for spinal MRI, cervical and thoracic spinal cord lesions were the most commonly observed. According to binary logistic regression analysis, FAR was an independent risk factor for the severity of neurological deficits (odds ratio = 1.717; 95% confidence interval = 1.191\u20132.477;\n                      <jats:italic>P<\/jats:italic>\n                      = 0.004).
