Abbreviations: OR: odds ratio; CI: confidence interval; APACHEII: acute physiology and chronic health valuation II; GCS: Glasgow coma scale; SOFA: sequential organ failure assessment; PDW: platelet distribution width; PT: prothrombin time; INR: international normalized ratio; APTT: activated partial thromboplastin time
^a Note that the odds ratio corresponds to a unit increase in the variable; ^b The odds ratio was adjusted for all significant variables of the univariate logistic regression analysis
