Baseline imbalance between patients with and without treatment of rhTM was adjusted using an inverse probability of treatment weighting using propensity scores composed of the following independent variables: severe postpartum hemorrhage, placental abruption, and preeclampsia/eclampsia, including hemolysis, elevated liver enzymes, and low platelet syndrome, initial platelet counts, D-dimer levels, fibrinogen levels, and prothrombin time–international normalized ratio (PT–INR). This evidence concerns the gene F2 and placental abruption.
