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.
