A Comparison of Physiologic Third‐Stage Care, Expectant Management, and Oxytocin Prophylaxis in the Prevention of Postpartum Hemorrhage Following Physiologic Labor and Birth: A Systematic Review

Further research is needed to improve evidence certainty, focus on patient-important outcomes, and enhance generalizability.
