Figure 1:

Plots of serum Ang-2 concentrations. Median serum Ang-2 was significantly higher in the nonsurvivors than the survivors using Mann–Whitney U test [112.50 (IQR 71.95–153.80) versus 78.55 (53.33–117.20); P< 0.0001]. Median serum Ang-2 was significantly higher in the male nonsurvivors than the male survivors using Mann–Whitney U test [119.80 (IQR 76.98–161.60) versus 78.40 (51.45–118.50); P< 0.0001]. No significant difference of median serum Ang-2 was found between female nonsurvivors and female survivors using Mann–Whitney U test [91.20 (IQR 67.20–142.90) versus 80.20 (59.00–117.70); P = 0.249].
