Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The recent four RCTs evaluating effects of RBC storage age on morbidity and mortality found no statistically significant adverse effects of longer stored RBC compared to shorter storage ages. Unfortunately, none of these RCTs had sufficient numbers of subjects receiving RBC at either storage age extreme to identify consequences of RBC transfusion at these limits. To better investigate effects of RBC storage age on clinical outcomes, this study will perform secondary meta-analyses of merged common patient data elements -individual patient data (IPD) meta-analysis (IPDMA) - from the nearly 33,000 subjects enrolled in the four RCTs.
