  1. Data missing for two participants in each group.
  2. Note: Sample size differed slightly for basic laboratory features. Serum WBC count: AUT, n = 101; TYP, n = 52. Serum IgG/IgM/IgA: AUT, n = 95; TYP, n = 52. CSF WBC count, n = 63. CSF albumin quotient: n = 61. Body mass index sample size was AUT (serum), n = 85; TYP, n = 47; AUT (CSF), n = 64
