The primary outcome was a composite of abnormal condition at birth or major neonatal morbidity. UCR was categorized as normal (&lt;\u200a0.9) or abnormal (\u2265\u200a0.9). UCR was assessed by gestational age at measurement interval to delivery, and by individual linear regression coefficient in women with two or more measurements.<\/jats:p><jats:p>\n          Results\u2002856 women had 2770 measurements; 696 (81\u200a%) had more than one measurement (median 3 (IQR 2\u20134). At inclusion, 63 (7\u200a%) a UCR \u2265\u200a0.9. These delivered earlier and had a lower birth weight and higher incidence of adverse outcome (30\u200a% vs. 9\u200a%, relative risk 3.2; 95\u200a%CI 2.1\u20135.0) than women with a normal UCR at inclusion. Repeated measurements after an abnormal UCR at inclusion were abnormal again in 67\u200a% (95\u200a%CI 55\u201380), but after a normal UCR the chance of finding an abnormal UCR was 6\u200a% (95\u200a%CI 5\u20137\u200a%). The risk of composite adverse outcome was similar using the first or subsequent UCR values.<\/jats:p><jats:p>\n          Conclusion\u2002An abnormal UCR is likely to be abnormal again at a later measurement, while after a normal UCR the chance of an abnormal UCR is 5\u20137\u200a% when repeated weekly. Repeated measurements do not predict outcome better than the first measurement, most likely due to the most compromised fetuses being delivered after an abnormal UCR.<\/jats:p>","DOI":"10.1055\/a-1511-8293","type":"journal-article","created":{"date-parts":[[2021,11,12]],"date-time":"2021-11-12T18:40:53Z","timestamp":1636742453000},"page":"56-67","source":"Crossref","is-referenced-by-count":4,"title":["Longitudinal Doppler Assessments in Late Preterm Fetal Growth Restriction"],"prefix":"10.1055","volume":"44","author":[{"given":"Bronacha","family":"Mylrea-Foley","sequence":"additional","affiliation":[{"name":"Institute for Reproductive and Developmental Biology, Department of Metabolism, Digestion and Reproduction, Imperial College London, UK"},{"name":"Queen Charlotte\u02bcs and Chelsea Hospital, Imperial College Healthcare NHS Trust, London W12 0HS"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hans","family":"Wolf","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Amsterdam University Medical Center (Location AMC), University of Amsterdam, Amsterdam, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tamara","family":"Stampalija","sequence":"additional","affiliation":[{"name":"Unit of Fetal Medicine and Prenatal Diagnosis, Institute for Maternal and Child Health, IRCCS Burlo Garofolo, Trieste, Italy"},{"name":"Department of Medicine, Surgery and Health Sciences, University of Trieste, Trieste, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christoph","family":"Lees","sequence":"additional","affiliation":[{"name":"Institute for Reproductive and Developmental Biology, Department of Metabolism, Digestion and Reproduction, Imperial College London, UK"},{"name":"Queen Charlotte\u02bcs and Chelsea Hospital, Imperial College Healthcare NHS Trust, London W12 0HS"},{"name":"Department of Gynecology and Obstetrics, UZ Leuven and Department of Regeneration and Development, KU Leuven, Leuven, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"B.","family":"Arabin","sequence":"additional","affiliation":[{"name":"Department of Obstetrics Charite, Humboldt University Berlin and Clara Angela Foundation, Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Berger","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Medical University of Innsbruck, Innsbruck, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"E.","family":"Bergman","sequence":"additional","affiliation":[{"name":"Department of Women\u2019s and Children\u2019s Health, Uppsala University, Uppsala, Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Bhide","sequence":"additional","affiliation":[{"name":"Fetal Medicine Unit, St George\u2019s University Hospitals NHS Foundation Trust and Molecular & Clinical Sciences Research Institute, St George\u2019s, University of London, London, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C.
