Table 3. Independent relationship of BMI with factor IX and clot strength at serial timepoints after injury.

Independent relationship of BMI and factor IX activity at serial timepoints after injury

	Factor IX (% activity) per 5 kg/m² increase in BMI	CI			p-value
0h	7.79	1.51	-	14.06	0.015
6h	13.88	4.80	-	22.95	0.003
12h	9.30	1.74	-	16.87	0.016
24h	7.83	-2.44	-	18.10	0.133
48h	15.71	3.93	-	27.50	0.010
120h	28.21	3.47	-	52.93	0.027

Covariates at each timepoint: age, injury severity, gender, and all products (pRBC, FFP, PLTs) received up to that timepoint. P-value bolded for <0.05.

Independent relationship of BMI and clot strength (MA) at serial timepoints after injury

	CK MA change (mm) per 5 kg/m² increase in BMI	CI			p-value
0h	1.01	0.39	-	1.62	0.002
6h	1.24	0.39	-	2.07	0.004
12h	1.17	0.36	-	1.97	0.005
24h	0.95	0.08	-	1.82	0.032
48h	0.35	-0.57	-	1.27	0.455
120h	0.63	-1.03	-	2.28	0.449

Covariates at each timepoint: age, injury severity, gender, and all products (pRBC, FFP, PLTs) received up to that timepoint. P-value bolded for <0.05. CK MA= citrated kaolin TEG maximum amplitude (mm).
