LGI1 and viral encephalitis: Removal of the DRE or the memory impairment components of the composite outcome measure did not alter the direction or significance of association of covariates (Tables S8 and S9, respectively), and exclusion of the mRS component revealed similar findings (Table S10), with only one covariate no longer significantly associated with 12-month outcome (anti-LGI1 Ab-mediated encephalitis diagnosis; OR 1.64; 95% CI 0.72–3.75; p = 0.244).
