Probability of in-hospital mortality upon admission among the entire patient cohort (a) and patients with septic shock (b). Probabilities are according to their concentrations of plasma pancreatic stone protein/regenerating protein (PSP/reg) (crosses), interleukin-6 (IL-6) (open circles), and procalcitonin (PCT) (closed circles). Gradients of grey correspond to quartiles of biomarker concentrations.
