Limitations
Main limitation for this systematic review and meta-analysis was the low rate of reporting variables related to the coagulopathy and blood products transfusion. Moreover, no studies highlighted causes of bleeding events in their respective population cohort, focusing on mere reporting number of cases without confounding factors. As long as head-to-head comparisons are lacking in this setting and the major shortages of reporting in some studies, we were unable to properly elucidate associated factors for FET-related coagulopathies.
