Fig. 1 Decision tree analysis with peak procalcitonin (PCT) as the principal discriminator for prediction of bloodstream infection (BSI) in patients with fever (n = 262). (a) Branch of the decision tree in cases where peak PCT was ≥2.45 ng/mL. (b) Branch with peak PCT levels that are lower than the cut-off value. Endpoint boxes include outcome (BSI or No BSI), probability (Pr) of outcome, and number (n) of cases included in the node during analysis. ASAT, aspartate aminotransferase; RR, respiratory rate.
