Singleton pregnancies &gt;\u200a37\u200a+\u200a0 weeks with ultrasound-estimated fetal weight (EFW) within 7 days before delivery were included. The study population was divided into four groups: Group 1 (false-negative): EFW &lt;\u200a4000\u200ag\/BW \u2265\u200a4000\u200ag; Group 2 (true-positive): EFW \u2265\u200a4000\u200ag\/BW \u2265\u200a4000\u200ag; Group 3 (false-positive): EFW \u2265\u200a4000\u200ag\/BW &lt;\u200a4000\u200ag; and Group 4 (true-negative): EFW &lt;\u200a4000\u200ag\/BW &lt;\u200a4000\u200ag.<\/jats:p><jats:p>\n          Results\u2002As expected, the highest secondary cesarean section (sCS) rate was found in Group 2 (true-positive) (30.62\u200a%), compared with only 17.68\u200a% in Group 4 (true-negative). The sCS rate in the false-positive Group 3 was significantly higher (28.48\u200a%) in comparison with the false-negative Group 1 (21.22\u200a%; OR 1.48; 95\u200a% CI, 1.16 to 1.89; P\u200a=\u200a0.002). In comparison with the true-negative Group 4, univariate analyses showed significantly higher rates for sCS in all other groups: odds ratio (OR) 2.06 for Group 2 (95\u200a% CI, 1.74 to 2.42; P\u200a&lt;\u200a0.001), 1.85 for Group 3 (95\u200a% CI, 1.54 to 2.22, P &lt;\u200a0.001), and 1.25 for Group 1 (95\u200a% CI, 1.05 to 1.49; P &lt;\u200a0.01). No significant differences were found for NO between Groups 1 and 3 for the parameters 5-min Apgar &lt;\u200a7 (P\u200a=\u200a0.75), pH &lt;\u200a7.1 (P\u200a=\u200a0.28), or NICU admission (P\u200a=\u200a0.54). However, there was a significantly higher chance for shoulder dystocia in Group 1 compared with Group 3 (OR 4.58; 95\u200a% CI, 1.34 to 24.30; P\u200a=\u200a0.008).<\/jats:p><jats:p>\n          Conclusion\u2002Sonographic EFW inaccuracies in fetal macrosomia appear to have a greater impact on the mode of delivery than birth weight itself. Underestimation of fetal weight may be associated with a higher probability of shoulder dystocia.<\/jats:p>","DOI":"10.1055\/a-1205-0191","type":"journal-article","created":{"date-parts":[[2020,8,7]],"date-time":"2020-08-07T02:55:40Z","timestamp":1596768940000},"page":"e56-e64","source":"Crossref","is-referenced-by-count":13,"title":["Influence of Sonographic Fetal Weight Estimation Inaccuracies in\u00a0Macrosomia on Perinatal Outcome"],"prefix":"10.1055","volume":"43","author":[{"given":"Jutta","family":"Pretscher","sequence":"additional","affiliation":[{"name":"Obstetrics and Gynecology, Friedrich-Alexander University Erlangen-Nuremberg, Erlangen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sven","family":"Kehl","sequence":"additional","affiliation":[{"name":"Obstetrics and Gynecology, Friedrich-Alexander University Erlangen-Nuremberg, Erlangen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patrick","family":"Stelzl","sequence":"additional","affiliation":[{"name":"Obstetrics and Gynecology, Friedrich-Alexander University Erlangen-Nuremberg, Erlangen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Florian Matthias","family":"Stumpfe","sequence":"additional","affiliation":[{"name":"Obstetrics and Gynecology, Friedrich-Alexander University Erlangen-Nuremberg, Erlangen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andreas","family":"Mayr","sequence":"additional","affiliation":[{"name":"Department of Medical Biometry, Informatics and Epidemiology, Faculty of Medicine, University of Bonn, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthias","family":"Schmid","sequence":"additional","affiliation":[{"name":"Department of Medical Biometry, Informatics and Epidemiology, Faculty of Medicine, University of Bonn, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christian","family":"Staerk","sequence":"additional","affiliation":[{"name":"Department of Medical Biometry, Informatics and Epidemiology, Faculty of Medicine, University of Bonn, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ralf","family":"Schild","sequence":"additional","affiliation":[{"name":"Obstetrics and Gynecology, DIAKOVERE gGmbH, Hannover, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matthias W.","family":"Beckmann","sequence":"additional","affiliation":[{"name":"Obstetrics and Gynecology, Friedrich-Alexander University Erlangen-Nuremberg, Erlangen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Florian","family":"Faschingbauer","sequence":"additional","affiliation":[{"name":"Obstetrics and Gynecology, Friedrich-Alexander University Erlangen-Nuremberg, Erlangen, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2020,8,6]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"1341","DOI":"10.1016\/s0140-6736(18)31928-7","article-title":"Global epidemiology of use of and disparities in caesarean sections","volume":"392","author":"T Boerma","year":"2018","journal-title":"Lancet"},{"key":"ref2","doi-asserted-by":"publisher","first-page":"745","DOI":"10.1111\/1471-0528.13592","article-title":"Association between rates of caesarean section and maternal and neonatal mortality in the 21st century: a worldwide population-based ecological study with longitudinal data","volume":"123","author":"J Ye","year":"2016","journal-title":"BJOG: an international journal of obstetrics and gynaecology"},{"key":"ref3","doi-asserted-by":"publisher","first-page":"57","DOI":"10.1186\/s12978-015-0043-6","article-title":"What is the optimal rate of caesarean section at population level?
