Trial Outcomes & Findings for Study of Tranexamic Acid During Air and Ground Medical Prehospital Transport Trial (STAAMP Trial) (NCT NCT02086500)

NCT ID: NCT02086500

Last Updated: 2020-09-10

Results Overview

Because not all patients had available data regarding 30-day mortality (patients were discharged and there 30-day outcome was unable to be determined) there may be differences between the 30Day mortality relative to the other outcomes. There were 5 and 4 patients from each arm that did not have 30-day outcome and thus are different.
