Denver Health has conducted the Control of Major Bleeding After Trauma (COMBAT) clinical research study, which aimed to improve trauma care for all patients (https://www.denverhealth.org/services/trauma/for-professionals-2/research-publications/combattrial). The study began in April 2014 and concluded in March of 2017. In collaboration with the University of Colorado Anschutz Medical Campus, longitudinal plasma samples collected from the COMBAT trial were analyzed by MS-based proteomics and metabolomics (available on Metabolomics Workbench).
