Abbreviations: CI, confidence interval; FFP, fresh-frozen plasma; IQR, interquartile range; OR, odds ratio; PLTs, platelets; RBCs, red blood cells.
Median volume and interquartile range for those who received the blood component.
Models included RBC, PLT, FFP, age (centered on mean), gender, race, medications (antibacterials, antimicrobials, antifungals, antivirals, immunosuppressants, insulin, statin), diabetes, cardiovascular disease, cancer, and surgery (cardiovascular, digestive tract, other).
Patients who received PLT or FFP were excluded.
Adjusted model also included volume (liters) of RBC units. Only subjects receiving RBCs were included.
