Methods: This was a randomized controlled trial that enrolled 1,061 low-risk pregnant women: 513 in the control group (routine ultrasound performed at 30th\u201333rd weeks) and 548 in the study group (with an additional ultrasound at 35th\u201337th weeks). FGR was defined as a fetus with an estimated fetal weight (EFW) below the 10th percentile. p values &lt; 0.05 were considered statistically significant. Results: The ultrasound at 35\u201337 weeks had an overall accuracy of FGR screening of 94%. Spearman\u2019s correlation coefficient between EFW and birthweight centile was higher for at 35\u201337 weeks\u2019 ultrasound (\u03c1 = 0.75) compared with 30\u201333 weeks\u2019 ultrasound (\u03c1 = 0.44). The study group had a lower rate of operative vaginal deliveries (24.4% vs. 39.3%, p = 0.005) and cesarean deliveries for nonreassuring fetal status (16.8% vs. 38.8%, p &lt; 0.001). Discussion\/Conclusion: A later ultrasound (35\u201337 weeks) had a high accuracy for detection of FGR and had a higher correlation between EFW and birthweight centiles. Furthermore, it was also associated with lower adverse perinatal outcomes compared to an earlier ultrasound. <\/jats:p>","DOI":"10.1159\/000527112","type":"journal-article","created":{"date-parts":[[2022,12,19]],"date-time":"2022-12-19T22:22:12Z","timestamp":1671488532000},"page":"425-433","source":"Crossref","is-referenced-by-count":6,"title":["Routine Ultrasound at 30th\u201333rd weeks versus 30th\u201333rd and 35th\u201337th weeks in Low-Risk Pregnancies: A Randomized Trial"],"prefix":"10.1159","volume":"49","author":[{"given":"Catarina","family":"Policiano","sequence":"first","affiliation":[]},{"given":"Jorge M.","family":"Mendes","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4074-638X","authenticated-orcid":false,"given":"Andreia","family":"Fonseca","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3468-4231","authenticated-orcid":false,"given":"Joana","family":"Barros","sequence":"additional","affiliation":[]},{"given":"Sara","family":"Vargas","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9828-8772","authenticated-orcid":false,"given":"Margarida","family":"Cal","sequence":"additional","affiliation":[]},{"given":"In\u00eas","family":"Martins","sequence":"additional","affiliation":[]},{"given":"Catarina","family":"Carvalho","sequence":"additional","affiliation":[]},{"given":"Diana","family":"Martins","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4370-369X","authenticated-orcid":false,"given":"Nuno","family":"Clode","sequence":"additional","affiliation":[]},{"given":"Luis M.","family":"Graca","sequence":"additional","affiliation":[]}],"member":"127","published-online":{"date-parts":[[2022,12,19]]},"container-title":["Fetal Diagnosis and Therapy"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/fdt\/article-pdf\/49\/9-10\/425\/3987905\/000527112.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/fdt\/article-pdf\/49\/9-10\/425\/3987905\/000527112.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T15:23:08Z","timestamp":1745421788000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000527112"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022]]},"references-count":0,"journal-issue":{"issue":"9-10","published-online":{"date-parts":[[2023,2,1]]},"published-print":{"date-parts":[[2023,2,7]]}},"URL":"https:\/\/doi.org\/10.1159\/000527112","archive":["Portico"],"relation":{},"ISSN":["1015-3837","1421-9964"],"issn-type":[{"value":"1015-3837","type":"print"},{"value":"1421-9964","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022]]}}}
