The study aimed to evaluate the performance of each reference and determine which reference most accurately identifies small for gestational age (SGA) infants at risk of perinatal mortality and morbidity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Material and Methods<\/jats:title>\n                    <jats:p>This population\u2010based cohort study included 1\u2009126\u2009059 singleton term births in Sweden from 2010 to 2020. Data were obtained from national registers, including the Swedish Medical Birth Register and the Swedish Neonatal Quality Register. Birthweight centiles were calculated using each growth reference. Adverse perinatal outcomes were categorized by severity and included stillbirth, neonatal death, and serious neonatal morbidity. Logistic regression models were used to assess predictive performance, and sensitivity and false positive rates (FPR) were calculated for SGA thresholds (&lt;3rd and &lt;10th centiles).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The distribution of birthweight centiles varied significantly across references. For SGA &lt;3rd centile, the rate ranged from 9.6% for Lindstr\u00f6m, 2.5% for Mar\u0161\u00e1l, 1.9% for WHO, to 0.7% for IG21st. All references showed similar overall predictive performance (C\u2010index\u2009\u2248\u20090.67) but with different discriminatory ability. The predicted risk of perinatal death increased at lower centiles for the Lindstr\u00f6m reference than for the Mar\u0161\u00e1l and WHO references, and at higher centiles for the IG21st reference. The Lindstr\u00f6m reference identified the highest proportion of infants as SGA and had the highest sensitivity but also the highest FPR for detecting adverse outcomes. The\u00a0IG21st reference classified the smallest proportion as SGA, resulting in the lowest sensitivity and FPR.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>While all fetal growth references showed comparable predictive ability for adverse perinatal outcomes, they differed substantially in sensitivity and FPR. When the top priority is to identify as many at\u2010risk fetuses as possible, Lindstr\u00f6m et\u00a0al.'s reference seems to be the best choice. However, when the top priority is a balanced sensitivity versus FPR, the WHO reference seems most suitable for clinical practice in this population of term births.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/aogs.70136","type":"journal-article","created":{"date-parts":[[2026,1,29]],"date-time":"2026-01-29T05:42:58Z","timestamp":1769665378000},"page":"466-478","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Differences in prediction of adverse perinatal outcome in term pregnancies by choice of fetal growth reference: A validation study"],"prefix":"10.1111","volume":"105","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4427-1075","authenticated-orcid":false,"given":"Linda","family":"Lindstr\u00f6m","sequence":"first","affiliation":[{"name":"Department of Women's and Children's Health Uppsala University  Uppsala Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8413-9274","authenticated-orcid":false,"given":"Fredrik","family":"Ahlsson","sequence":"additional","affiliation":[{"name":"Department of Women's and Children's Health Uppsala University  Uppsala Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ove","family":"Axelsson","sequence":"additional","affiliation":[{"name":"Department of Women's and Children's Health Uppsala University  Uppsala Sweden"},{"name":"Centre for Clinical Research S\u00f6rmland Uppsala University  Eskilstuna Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2925-3779","authenticated-orcid":false,"given":"Michaela","family":"Granfors","sequence":"additional","affiliation":[{"name":"Division of Clinical Epidemiology, Department of Medicine (Solna) Karolinska Institutet  Stockholm Sweden"},{"name":"Department of Obstetrics and Gynecology Sahlgrenska University Hospital  Gothenburg Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Erik","family":"Lampa","sequence":"additional","affiliation":[{"name":"Department of Medical Sciences Uppsala University  Uppsala Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria","family":"Nelander","sequence":"additional","affiliation":[{"name":"Department of Women's and Children's Health Uppsala University  Uppsala Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna\u2010Karin","family":"Wikstr\u00f6m","sequence":"additional","affiliation":[{"name":"Department of Women's and Children's Health Uppsala University  Uppsala Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,1,28]]},"reference":[{"key":"e_1_2_13_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1479-828X.2007.00742.x"},{"key":"e_1_2_13_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/uog.12391"},{"key":"e_1_2_13_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/uog.22151"},{"key":"e_1_2_13_5_1","doi-asserted-by":"publisher","DOI":"10.1080\/14767058.2017.1376048"},{"key":"e_1_2_13_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/uog.20272"},{"key":"e_1_2_13_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/uog.15884"},{"key":"e_1_2_13_8_1","doi-asserted-by":"publisher","DOI":"10.1002\/uog.1806"},{"key":"e_1_2_13_9_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1469-0705.1993.03060378.x"},{"key":"e_1_2_13_10_1","doi-asserted-by":"publisher","DOI":"10.1002\/sim.8000"},{"key":"e_1_2_13_11_1","unstructured":"Swedish Society of Obstetrics and Gynecology.Rekommendationer f\u00f6r fetometri.
