Data are presented as number (percentage)
^aPatients with a total score ≥ 3 before delivery or ≥ 2 after delivery were considered as high-risk patients, and the others, as low-risk patients
^bMissed prophylaxis opportunities for postnatal patients include no early mobilization, no use of any mechanical methods, and no use of anticoagulants, while for antenatal patients they include no use of any mechanical methods and no use of anticoagulants since antenatal patients always practiced mobilization
^cEarly mobilization refers to mobilization after delivery
^dThe percentage of “no use of anticoagulants” refers to women who did not take anticoagulants and were stratified as high risk
