LGI1 and teratoma: Testing some of the single variables investigated above in a multivariable logistic regression model (parameters included: age, follow-up time and CSF-NfL level at diagnosis) similarly revealed that higher CSF-NfL at diagnosis was associated with a poorer outcome in idiopathic/teratoma associated NMDAR-AE and LGI1-AE patients combined (OR 11.97, 95% CI 1.22-117.01, p=0.033) (Table 2).
