ICU, intensive care unit.
Calculated using the Cochran-Mantel-Haenszel test, adjusting for plasma transfused in the first 24 hours.
The stratified log-rank test was used to test treatment effect, controlling for plasma transfused in the first 24 h.
Wilcoxon rank sum test was used to compare time to death for patients who died. Because of small numbers, this comparison was not adjusted for plasma.
The van Elteren test was used to compare medians, adjusting for amount of plasma transfused in the first 24 hours.
Generalized logit mixed model was fitted to test treatment effect, including plasma transfused in the first 24 hours as random effect.
Includes long-term care facility, skilled nursing facility, rehabilitation facility, acute care hospital, assisted living, psychiatric facility, jail, and unknown.
