| VTE – venous thromboembolism; DVT – deep venous thrombosis; PE – pulmonary embolism; APS – antiphospholipid syndrome; LMWH – low-molecular-weight heparin. * “Confirmed Time” refers to the time of initial diagnosis of VTE before and/or after delivery. Day 2, Day 3, etc. indicate the second or third day, respectively, after childbirth. ** Artificial reproductive technology/in vitro fertilization and ovarian hyperstimulation syndrome are risk factors for VTE antenatally, so they are not included in this table for postpartum VTE assessment. | |||||
