Comparison of the ABC Score, Original MTS, and Revised MTS at time zero for prediction of Massive Transfusion in Trauma Patients^*

Model	n	Need for MT by 6 hours				Need for MT by 24 hours
Model	n	OR MT (95% CI)	AUC (95% CI)	p-value	HL	OR MT	AUC (95% CI)	p-value	HL
Revised MTS	97	1.8 (1.2–2.6)	0.68 (0.57–0.79)	0.003	p=0.59	2.2 (1.4–3.3)	0.72 (0.61–0.83)	0.001	p=0.62
Original MTS	83	1.3 (0.9–1.7)	0.60 (0.48–0.72)	0.154	p=0.57	1.3 (0.9–1.7)	0.60 (0.47–0.72)	0.146	p=0.83
ABC Score	189	1.3 (1.0–1.8)	0.58 (0.50–0.67)	0.051	p=0.88	1.0 (0.8–1.4)	0.51 (0.42–0.60)	0.799	p=0.83

accounting for hemorrhagic deaths within the interval time period; Hosmer-Lemeshow (HL) goodness of fit performed for each model

MTS: Massive transfusion score, ABC: Assessment of blood consumption score, n: number of patients, OR: odds ratio, MT: massive transfusion, AUC: area under the curve, CI: confidence interval; HL: Hosmer-Lemeshow goodness of fit
