Meanwhile, the simple linear regression analysis and multiple linear regression analysis revealed that mRS score at the 6-month follow-up examination was not associated with serum/CSF LGI1 antibody titers, abnormal brain MRI, hyponatremia, FBDS, CSF protein concentrations, CSF white blood cell count, CSF immunoglobulin G, A, and M titers, and CSF lactate levels. This evidence concerns the gene LGI1 and Hyponatremia.
