Predictive value of thrombocytopenia for bloodstream infection in patients with sepsis and septic shock

Figure 1 Platelet count over time stratified according to blood culture results. Data are median (25^th, 75^th percentile).

Figure 2 Box plot showing the percentage decline of platelet counts and lowest platelet count. A: Eighty-five bacterial infection episodes showed a higher percentage decline of platelet count (PPC); B: Lower levels of platelet count than nonbacterial events (P < 0.001) by Mann-Whitney U test; C: The PPC was not significantly different in the group with gram-positive bacteraemia, gram-negative bacteraemia, and fungal infection (P > 0.05). Data are presented with median lines, 25- and 75-percentile boxes, and 10- and 90-percentile error bars. PPC: The percentage decline of platelet counts. The (*) and (o) in the figure are Scatter data.

Figure 3 Receiver operating characteristic curves of serum biomarkers for the positive diagnosis of bacterial species in critically ill patients with clinical sepsis and sepsis shock. ROC: Receiver operating characteristic; PCT: Procalcitonin; CRP: C-reactive protein.
