The double correlation coefficient, DIC, R = 0.57684 (p < 0.000001); Pre-DIC + DIC, R = 0.51303 (p < 0.000001); DIC, disseminated intravascular coagulation; Non-DIC, DIC score ≤ 4; Pre-DIC, DIC score 5 or 6; DIC, DIC score ≥ 7 using the Japanese Ministry of Health, Labor and Welfare diagnostic criteria. PT-INR, prothrombin time–international normalized ratio.
