Universidad de Zaragoza (orcid)0000-0001-9585-0187 Prediction of large for gestational age by ultrasound at 35 weeks and impact of ultrasound-delivery interval: Comparison of 6 standards 2021 Access copy available to the general public Unrestricted Objective: The aim of the study was to assess the predictive ability of the ultrasound estimated percentile weight (EPW) at 35 weeks to predict large for gestational age (LGA) at term delivery according to 6 growth standards, including population, population-customized, and international references. The secondary objectives were to determine its predictive ability to detect adverse perinatal outcomes (APOs) and whether the ultrasound-delivery interval influences the detection rate of LGA newborns. Methods: This was a retrospective cohort study of 9, 585 singleton pregnancies. Maternal clinical characteristics, fetal ultrasound data obtained at 35 weeks, and pregnancy and perinatal outcomes were used to calculate EPWs to predict LGAs at delivery according to the customized and the non-customized (NC) Miguel Servet University Hospital (MSUH), the customized Figueras, the NC Fetal Medicine Foundation (FMF), the NC INTERGROWTH-21st, and the NC World Health Organization (WHO) standards. Results: For a 10% false-positive rate, detection rates for total LGAs at delivery ranged from 31.2% with the WHO (area under the curve [AUC] 0.77; 95% confidence interval [CI], 0.76-0.79) to 56.5% with the FMF standard (AUC 0.85; 95% CI, 0.84-0.86). Detection rates and values of AUCs to predict LGAs by ultrasound-delivery interval (range 1-6 weeks) show higher detection rates as the interval decreases. APO detection rates ranged from 2.5% with the WHO to 12.6% with the Figueras standard. Conclusion: The predictive ability of ultrasound estimated fetal weight at 35 weeks to detect LGA infants is significantly greater for FMF and MSUH NC standards. In contrast, the APO detection rate is significantly greater for customized standards. The shorter ultrasound-delivery interval relates to better prediction rates. info:eu-repo/semantics/closedAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 2.208 2021 OBSTETRICS & GYNECOLOGY 66 / 85 = 0.776 2021 Q4 T3 0.935 2021 Embryology 2021 Q1 Radiology, Nuclear Medicine and Imaging 2021 Q1 Pediatrics, Perinatology and Child Health 2021 Q1 Medicine (miscellaneous) 2021 Q1 4.2 2021 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Esteban, L.M.
