Participants were randomly assigned to the dienogest group or COCs group. The primary outcome was the level of adenomyosis\u2010associated pain from before to 6\u00a0months after treatment measured by a visual analog scale (VAS). Changes in the uterine bleeding pattern, uterine volume, and uterine artery blood flow were also reported.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The VAS score of pain was significantly decreased in both groups; however, the decreased rate was more pronounced in the dienogest group (3.21\u00a0\u00b1\u00a01.18) in comparison with the COCs group (4.92\u00a0\u00b1\u00a01.22). Bleeding pattern was improved greatly; uterine volume and uterine artery blood flow decreased significantly in the dienogest group. However, women in the dienogest group reported a higher rate of side effects.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Dienogest and COCs are effective in treating adenomyosis\u2010associated symptoms after 6\u00a0months of use but dienogest is more effective. The decrease in uterine volume and uterine artery blood flow may be the cause of the treatment effect. Dienogest carries a higher risk of side effects.<\/jats:p><jats:p>Clinical trial.gov: NCT03890042.<\/jats:p><\/jats:sec>","DOI":"10.1002\/ijgo.13600","type":"journal-article","created":{"date-parts":[[2021,1,17]],"date-time":"2021-01-17T16:48:31Z","timestamp":1610902111000},"page":"263-269","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":40,"title":["Comparison of dienogest versus combined oral contraceptive pills in the treatment of women with adenomyosis: A randomized clinical trial"],"prefix":"10.1002","volume":"154","author":[{"given":"Ahmed I.","family":"Hassanin","sequence":"first","affiliation":[{"name":"Department of Obstetrics and Gynecology Faculty of Medicine Assiut University Assiut Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ahmed A.","family":"Youssef","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology Faculty of Medicine Assiut University Assiut Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Asmaa M.","family":"Yousef","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology Faculty of Medicine Assiut University Assiut Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohammed K.","family":"Ali","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology Faculty of Medicine Assiut University Assiut Egypt"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2021,2,11]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1148\/rg.2018180080"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejogrb.2020.08.019"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.3390\/jcm9020485"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/ijgo.13341"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.fertnstert.2018.01.013"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1093\/humupd\/dmz049"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jmig.2017.08.653"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajog.2009.03.021"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1093\/humrep\/dep469"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1080\/09513590.2019.1683818"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1447-0756.2009.01076.x"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0015-0282(03)00794-5"},{"key":"e_1_2_7_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.contraception.2010.06.011"},{"key":"e_1_2_7_15_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.contraception.2015.05.015"},{"issue":"5","key":"e_1_2_7_16_1","first-page":"380","article-title":"Chronic pelvic pain in women","volume":"93","author":"Speer LM","year":"2016","journal-title":"Am Fam Physician"},{"key":"e_1_2_7_17_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0885-3924(99)00092-5"},{"key":"e_1_2_7_18_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.gmit.2016.06.002"},{"issue":"3","key":"e_1_2_7_19_1","first-page":"119","article-title":"Color Doppler ultrasound to improve the diagnostic accuracy of the transvaginal ultrasound in the diagnosis of adenomyosis: a cross\u2010sectional study","volume":"6","author":"Abd El Aal DEM","year":"2016","journal-title":"Journal of Evidence\u2010Based Women\u2019s Health Journal Society"},{"key":"e_1_2_7_20_1","doi-asserted-by":"publisher","DOI":"10.1097\/GCO.0000000000000212"},{"key":"e_1_2_7_21_1","doi-asserted-by":"publisher","DOI":"10.2165\/11206320-000000000-00000"},{"key":"e_1_2_7_22_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejogrb.2017.01.002"},{"key":"e_1_2_7_23_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpag.2014.02.015"},{"key":"e_1_2_7_24_1","doi-asserted-by":"publisher","DOI":"10.1080\/03007995.2020.1744120"},{"key":"e_1_2_7_25_1","doi-asserted-by":"publisher","DOI":"10.3109\/09513590.2014.926882"},{"key":"e_1_2_7_26_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00404-015-3755-5"},{"key":"e_1_2_7_27_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.fertnstert.2017.07.021"},{"key":"e_1_2_7_28_1","doi-asserted-by":"publisher","DOI":"10.1111\/jog.13406"},{"key":"e_1_2_7_29_1","doi-asserted-by":"publisher","DOI":"10.1111\/jog.13674"},{"key":"e_1_2_7_30_1","doi-asserted-by":"publisher","DOI":"10.1111\/jog.13720"},{"key":"e_1_2_7_31_1","doi-asserted-by":"publisher","DOI":"10.1080\/09513590601005375"},{"key":"e_1_2_7_32_1","doi-asserted-by":"publisher","DOI":"10.1055\/s-0039-1695737"},{"key":"e_1_2_7_33_1","doi-asserted-by":"publisher","DOI":"10.1097\/OGX.0000000000000346"}],"container-title":["International Journal of Gynecology &amp;
