The remainder were considered low\u2010risk pregnancies and randomly divided into groups III and IV. In groups I, II and III cervical scoring in accordance with Westin was performed in weeks 24, 28 and 32. The incidence of births before 37 weeks of gestation was 5.6% in group I, 8.8% in group II, 1.5% in group III and 0.7% in group IV. In presence of the risk factors, 61% of the spontaneous preterm deliveries were predicted early in pregnancy. The predictive value of a normal cervical score was high (about 95%) in all groups. In uncomplicated pregnancies the predictive value of a pathological score was only 4% and for cervical dilatation, 6%. In the risk groups the predictive value of a pathological cervix was 3\u20105\u2010fold higher. Cervical examination in low\u2010risk pregnancies does not improve prediction of preterms but is a complement in a system for indication for preterm delivery in women with defined risk factors.<\/jats:p>","DOI":"10.3109\/00016348709015725","type":"journal-article","created":{"date-parts":[[2007,11,22]],"date-time":"2007-11-22T00:44:38Z","timestamp":1195692278000},"page":"507-512","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":23,"title":["Prediction of Preterm Birth"],"prefix":"10.1111","volume":"66","author":[{"given":"Ove Andreas","family":"Mortensen","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jonas","family":"Franklin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tord","family":"Lofstrand","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bernhard","family":"Svanberg","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2011,1,11]]},"reference":[{"key":"e_1_2_1_2_1","volume-title":"Ovarian dysfunction\u2014one risk factor for endometrial cancer","author":"Dahlgren E."},{"key":"e_1_2_1_3_1","first-page":"3069","article-title":"Gynekologisk skrapning\u2014v\u00e4rderingar, utbyte och kostnader","volume":"79","author":"Holst J.","year":"1971","journal-title":"L\u00e4kartidn"},{"key":"e_1_2_1_4_1","first-page":"4815","article-title":"Livmoderskrapning\u2014m\u00e5ste vi t\u00e4nka om?","volume":"79","author":"Bergstr\u00f6m H.","year":"1982","journal-title":"L\u00e4kartidn"},{"key":"e_1_2_1_5_1","unstructured":"HagstadA..Den mogna kvinnans gynekologi o sexualitet.University of G\u00f6teborg.1985 Thesis."},{"key":"e_1_2_1_6_1","unstructured":"JohanssonS..Female myocardial infarction in G\u00f6teborg.University of G\u00f6teborg Sweden1983 Thesis."},{"key":"e_1_2_1_7_1","first-page":"181","volume-title":"Supplemental Library User's Guide, Edition","author":"SAS INSTITUTE INC SUGJ","year":"1983"},{"key":"e_1_2_1_8_1","volume-title":"Statistical inference under order restrictions","author":"Barlow R E.","year":"1972"}],"container-title":["Acta Obstetricia et Gynecologica Scandinavica"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.3109%2F00016348709015725","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/obgyn.onlinelibrary.wiley.com\/doi\/pdf\/10.3109\/00016348709015725","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,21]],"date-time":"2023-10-21T19:21:50Z","timestamp":1697916110000},"score":1,"resource":{"primary":{"URL":"https:\/\/obgyn.onlinelibrary.wiley.com\/doi\/10.3109\/00016348709015725"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1987,1]]},"references-count":7,"journal-issue":{"issue":"6","published-print":{"date-parts":[[1987,1]]}},"alternative-id":["10.3109\/00016348709015725"],"URL":"https:\/\/doi.org\/10.3109\/00016348709015725","archive":["Portico"],"relation":{},"ISSN":["0001-6349","1600-0412"],"issn-type":[{"value":"0001-6349","type":"print"},{"value":"1600-0412","type":"electronic"}],"subject":[],"published":{"date-parts":[[1987,1]]},"assertion":[{"value":"2011-01-11","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
