Continuous variables were presented as median (interquartile range).
Categorical variables were presented as n (%).
CI, confidence interval; OR, odds ratio; SE, status epilepticus; WBC, white blood cell.
a
The CSF/blood glucose ratio was available in 16 patients with infectious and all patients with autoimmune etiology.
b
The IgG index was available in six patients with infectious and 20 patients with autoimmune etiology.
