Forward logistic regression models. No imputation of missing values was performed. (A) Consensus retrospective physician diagnosis (RPD) (n = 160), procalcitonin (PCT) included. (B) Forced RPD (n = 176), PCT included. (C) Unanimous RPD (n = 120), PCT included. For panels A–C, variables were added in the order A, B, C, D, E, F, and area under the curve (AUC) values were recalculated after each addition step. (D) Consensus RPD (n = 223), PCT excluded. (E) Forced RPD (n = 243), PCT excluded. (F) Unanimous RPD (n = 166), PCT excluded. For panels D–F, variables were added in the order A, D, G, H, I, J, and AUC values were recalculated after each addition step. Symbols, consistent with assignments in the online supplement, part 6, are as follows: A = SeptiScore; B = log₂PCT; C = maximum white blood cell count; D = number of systemic inflammatory response syndrome criteria; E = minimum core temperature; F = minimum white blood cell count; G = maximum mean arterial pressure; H = race/ethnicity; I = maximum core temperature; J = sex.
