Coagulation parameters of women with and without combined end point of severe acute maternal morbidity or mortality per categorized amount of blood loss. (A) Hemoglobin, (B) hematocrit, (C) platelet count, (D) fibrinogen, (E) aPTT, and (F) PT. Box plots of coagulation parameters per categorized amount of blood loss comparing women experiencing postpartum hemorrhage with and without the composite adverse outcome. Morbi-mortality comprises the composite adverse outcome of severe acute maternal morbidity, mortality, or need for surgical intervention. Circles are outliers. The box represents the 25th and 75th percentiles, and the whiskers are the upper and lower adjacent values.
