Note.—Unless otherwise indicated, data are number of patients, and data in parentheses are percentages. aPTT = activated partial thromboplastin time, DI = diffuse injury, P-GCS = postresuscitation Glasgow coma scale.

^*Data are median, and data in parentheses are the interquartile range.

^†Data are mean ± standard deviation.
