Data are mean ± SD.

DIC indicates disseminated intravascular coagulation; APTT, activated partial thromboplastin time; INR, international normalized ratio; sGPVI, soluble glycoprotein VI; CI, confidence interval; and NA, not applicable.

*

All DIC cases were positive for D-dimer (> 0.5 μg/mL), with 20 of 29 cases > 10 μg/mL (upper sensitivity limit of the assay).

sGPVI levels are adjusted for age and platelet count only.

sGPVI levels are adjusted for age, platelet count, underlying cause, and coagulation markers.
