LGI1 and Mydriasis: Although this included fewer observations, mydriasis (53/80 (66 %) vs. 11/40 (27.5 %) pcorr = 0.003) and circling (23/80 (29 %) vs. 1/40 (2.5 %) (pcorr = 0.009) remained significantly enriched in LGI1-antibody cats after multiple comparison correction, while salivation (55/80 (69 %) vs. 19/40 (47 %) was significant on raw p-value (uncorrected p = 0.04) (Supplementary Table 2).
