Normally distributed variables were presented as mean ± SD and compared using t-tests. Non-normally distributed variables were presented as median (IQR = 25–75th percentile) and were contrasted using the Mann-Whitney U-test. Categorical variables were described as number (percentage), and the chi-square test or Fisher's exact test was used for comparison between groups.
Anti-NMDAR encephalitis, anti-N-methyl-D-aspartate receptor encephalitis; PT, prothrombin time; APTT, activated partial thrombin time; TT, thrombin time; WBC, white blood cell; RBC, red blood cell.
