  1. a Se - sensitivity, Sp - specificity, LR+ - positive likelihood ratio, LR- - negative likelihood ratio.
  2. b Optimal scoring thresholds for tau and S100B, estimated in this study. Values are in pg/mL for tau, and in ng/mL for S100B.
  3. c Consensus scoring thresholds for tau and S100B, based on published literature.
