Red Cell Storage Duration Does Not Affect Outcome after Massive Blood Transfusion in Trauma and Nontrauma Patients: A Retrospective Analysis of 305 Patients

Table 3

Summary statistics of outcomes by quartiles of patient-specific mean storage duration of transfused red blood cells. Statistics reported as a percentage, mean ± standard deviation, or median [first quartile, third quartile]. Results reflect 305 patients included in the univariable analyses (see Methods). Medians and quartiles are reported when the sample skewness coefficient is >0.9 in absolute value.

Outcome variable	First quartile; (8.0–17.7 days)	Second quartile; (17.7–21.6 days)	Third quartile; (21.6–26.6 days)	Fourth quartile; (26.6–36.6 days)	Percent; missing
