Fig. 3From: Impact of initial coagulation and fibrinolytic markers on mortality in patients with severe blunt trauma: a multicentre retrospective observational studyClassification and regression tree (CART) analysis for 28-day mortality. In the CART analysis, platelet counts, fibrinogen, prothrombin time-international normalised ratio, and D-dimer were injected as explanatory variables. The black portion in each pie chart represents 28-day mortality. The names of each terminal node are groups A, B, C and D. Group A is considered a low-risk group, and the groups B and C are moderate-risk groups and group D is considered a high-risk groupBack to article page
