Further analysis of the three subtypes revealed that the AUCs of NLR at NMDAR, LGI1, and GABABR encephalitis were 0.859, 0.835, and 0.756; the AUCs of MLR at NMDAR, LGI1, and GABABR encephalitis were 0.763, 0.808, and 0.849; the AUCs of NLR combined with MLR (NLR + MLR) at NMDAR, LGI1, and GABABR encephalitis were 0.866, 0.849, and 0.849 (Table 3). This evidence concerns the gene LGI1 and viral encephalitis.
