B, partial regression coefficient; SE, standard error; β, standard partial regression coefficient; CI, confidence interval; R2, coefficient of determination; ANOVA, analysis of variance. Independent variables: platelet count, prothrombin time ratio, the fibrinogen level, the FDP levels, and the JAAM DIC score on admission.
