The obstetrical data are compared with the medical and psychological military draft board examinations. The mortality and morbidity rates were not significantly different from those of the total cohort of Norwegian conscripts, either in the forceps or in the vacuum group. Rotation of the fetal head with Kielland's forceps in midcavity extractions did not adversely affect the late results. A significantly elevated mean intelligence score was found in the forceps group, while the vacuum group did not differ from the national average.<\/jats:p>","DOI":"10.3109\/00016348409156718","type":"journal-article","created":{"date-parts":[[2009,12,8]],"date-time":"2009-12-08T17:58:26Z","timestamp":1260295106000},"page":"549-554","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":30,"title":["Boys Born by Forceps and Vacuum Extraction Examined at 18 Years of Age"],"prefix":"10.1111","volume":"63","author":[{"given":"Stein Tore","family":"Nilsen","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2011,1,11]]},"reference":[{"doi-asserted-by":"publisher","key":"e_1_2_1_2_1","DOI":"10.1136\/bmj.1.6155.7"},{"doi-asserted-by":"publisher","key":"e_1_2_1_3_1","DOI":"10.1016\/S0002-9378(20)90067-4"},{"key":"e_1_2_1_4_1","doi-asserted-by":"crossref","first-page":"153","DOI":"10.1111\/j.1600-0412.1981.tb00028.x","article-title":"Effect of instrumental delivery on the frequency and severity of retinal hemorrhages in the newborn","volume":"60","author":"Egge K.","year":"1981","journal-title":"Acta Obstet Gynecol Scand"},{"key":"e_1_2_1_5_1","first-page":"571","article-title":"Comparison of maternal and fetal effects of vacuum extraction with forceps or Cesarean deliveries","volume":"57","author":"Greis J.
