Fig. 1.
Box plot representing the time course of protein C concentrations (%) over the 2 weeks after admission to the intensive care unit in patients who never had sepsis in the intensive care unit (open boxes), those with sepsis (hatched boxes), and those with severe sepsis (including septic shock;closed boxes). Thedashed linerepresents the lower limit of normal for protein C activity (70%). Friedman test:P < 0.05 in each group over time. Multifactorial analysis of variance;P < 0.05 between groups. * P < 0.05 compared with no-sepsis group (Mann–Whitney U test with Bonferroni correction). $ P < 0.05 compared with sepsis group (Mann–Whitney U test with Bonferroni correction)
