The Kaplan-Meier curve of 5 control baboons (○) and 5 rhATIII-treated baboons (•) after lethal challenge with E coli. Animals surviving for 168 hours (7 days) were considered permanent survivors. Survival was significantly higher in the rhATIII-treated animals, as measured by log rank test (P = .002).
