Relations between tertiles of PTX3 concentration on day 1 and incident organ failures. New organ failures were defined as a change in each component of the SOFA score during the study to 3 or 4 from 0, 1 or 2 at baseline. Number of patients without organ-specific failure at study entry: respiration (525), coagulation (862), liver (896), cardiovascular (392), renal (715). P across tertiles by chi-square test.
