Evaluation of Potential Clinical Surrogate Markers of a Trauma Induced Alteration of Clotting Factor Activities

Figure 9

Clotting factor activities after multiple trauma according to amount of preclinical fluid resuscitation. Fib: fibrinogen; Ca: calcium. The results are presented by using boxplots. Bottom and top of the box indicate the 25th and 75th percentile, called interquartile range (IR). The median is represented by the horizontal bar within the box. Whiskers indicate spread (1.5 times IR). Logarithmic ordinate for better depiction. The Mann-Whitney U-test was performed with and (<1500 versus >1500 mL of preclinical fluid volume).
