2 July 2020	New search has been performed	For this update, published in 2020, we made these changes: 1. We changed the title from 'Progestogens or progestogen‐releasing intrauterine systems for uterine fibroids' to 'Progestogens or progestogen‐releasing intrauterine systems for uterine fibroids (other than preoperative medical therapy)'. 2. We updated the methodology in the review to include 'Risk of bias' assessment, implemented the GRADE approach to assess the quality of the body of evidence, and developed 'Summary of findings' tables.
