Estimated relative risks and 95% confidence intervals for abnormal TEG parameters versus CC+ in 391 patients. K-time >2.5 min, mA <55 mm, and platelet count <150 × 109/L were independently associated with CC+. ACT, activated clotting time. mA, maximum amplitude. LY30, lysis in 30 minutes. Plt, platelet count. CC, clinically evident coagulopathy.
