Primary Outcome Measures
NameTimeMethod
Patients Alive on Day 28, Having Had an Improvement in the DIC Score (Overt or Non-overt) by at Least 2 Points Between Baseline and Day 6 and Having Had no Worsening of the SOFA Score Between Baseline and Day 6.Day 28

Disseminated Intravascular Coagulation (DIC) ranges from 0 to 8 points, the higher the score the worse coagulation/outcome.

Sepsis-related Organ Failure Assessment (SOFA) is a composite score of scores for the respiratory, cardiovascular, hepatic, coagulation, renal and neurological systems. Each system is scored from 0 to 4 with a higher score given for worse organ function. The scores are then added together to give a total range from 0 to 24 with a higher score representing a worse outcome.
