Risk adjusted mortality OR by transfusion cutoff (before and after threshold) by age group^∗.

Age	Transfusion threshold	Mortality below threshold	Mortality above threshold	Odds ratio	Adjusted odds Ratio†	Adjusted odds Ratio‡
16-30	60 units	30.3%	67.7%	4.82 (2.23, 10.50)	4.31 (1.61, 11.56)	4.92 (1.92, 12.65)
31-55	48 units	32.8%	72.6%	5.41 (2.85, 10.27)	4.69 (2.10, 10.47)	5.54 (2.58, 11.93)
56-100	24 units	36.2%	77.0%	5.90 (3.52, 9.88)	8.80 (4.49, 17.24)	8.39 (4.37, 16.13)

OR = odds ratio; ICISS = international classification of disease injury severity; ScoreCPR = cardiopulmonary resuscitation.

^∗Transfusion defined as total unit volume from an approximate 1:1:1 ratio of PRBC:FFP:PLTS.

^†Risk adjusted by gender, comorbidities, ICISS, CPR event, injury mechanism, reliability adjustment.

^‡Risk adjusted by gender, comorbidities, ISS, CPR event, injury mechanism, reliability adjustment.
