We compared six prognostic models using multilevel logistic regression, where each subsequent model added a new variable to a base model that included maternal characteristics. Estimated fetal weight (EFW) and four Doppler ultrasound measurements were added in turn: umbilical artery pulsatility index (UA PI), middle cerebral artery pulsatility index (MCA PI), cerebroplacental ratio (CPR), and mean uterine artery pulsatility index (mUtA PI). The primary outcome was a composite adverse perinatal outcome, defined as perinatal mortality, emergency caesarean delivery for fetal distress, or neonatal admission. Discriminative ability was quantified with area under the curve (AUC).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Three data sets (<jats:italic>N<\/jats:italic>\u00a0=\u00a03284) were included.

Adding more ultrasound measurements did not improve further the discriminative ability. In subgroup analysis, the addition of EFW and UA PI improved AUC in both preterm (AUC from 0.711 to 0.795) and small for gestational age pregnancies (AUC from 0.729 to 0.770), but they did not improve the models in term delivery or normal growth subgroups.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Umbilical artery pulsatility index added prognostic value for adverse perinatal outcomes to the already available information, but the combination of other Doppler ultrasound measurements (MCA PI, CPR or UtA PI) did not improve further prognostic performance.<\/jats:p><\/jats:sec>","DOI":"10.1111\/ajo.13547","type":"journal-article","created":{"date-parts":[[2022,6,9]],"date-time":"2022-06-09T07:10:31Z","timestamp":1654758631000},"page":"19-26","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Added prognostic value of Doppler ultrasound for adverse perinatal outcomes: A pooled analysis of three cohort studies"],"prefix":"10.1111","volume":"63","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8371-3126","authenticated-orcid":false,"given":"Madeline F.","family":"Flanagan","sequence":"first","affiliation":[{"name":"Department of Obstetrics &amp; Gynaecology Monash University  Melbourne Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Charlotte A.","family":"Vollgraff Heidweiller\u2010Schreurs","sequence":"additional","affiliation":[{"name":"Department of Obstetrics &amp; Gynaecology Amsterdam UMC, location VUmc  Amsterdam The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wentao","family":"Li","sequence":"additional","affiliation":[{"name":"Department of Obstetrics &amp; Gynaecology Monash University  Melbourne Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wessel","family":"Ganzevoort","sequence":"additional","affiliation":[{"name":"Department of Obstetrics &amp; Gynaecology Amsterdam UMC, location AMC  Amsterdam The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marjon A.","family":"de Boer","sequence":"additional","affiliation":[{"name":"Department of Obstetrics &amp; Gynaecology Amsterdam UMC, location VUmc  Amsterdam The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alicia","family":"Vazquez\u2010Sarandeses","sequence":"additional","affiliation":[{"name":"Fetal Medicine Unit\u2010SAMID, Department of Obstetrics and Gynaecology, University Hospital 12 de Octubre, 12 de Octubre Research Institute (imas12) Complutense University of Madrid  Madrid Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ozhan M.","family":"Turan","sequence":"additional","affiliation":[{"name":"Departments of Obstetrics, Gynecology and Reproductive Sciences University of Maryland School of Medicine  Baltimore MD USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Patrick M.","family":"Bossuyt","sequence":"additional","affiliation":[{"name":"Department of Obstetrics &amp; Gynaecology Amsterdam UMC, location AMC  Amsterdam The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8337-550X","authenticated-orcid":false,"given":"Ben W.J.","family":"Mol","sequence":"additional","affiliation":[{"name":"Department of Obstetrics &amp; Gynaecology Monash University  Melbourne Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniel L.","family":"Rolnik","sequence":"additional","affiliation":[{"name":"Department of Obstetrics &amp; Gynaecology Monash University  Melbourne Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2022,6,9]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1097\/01.AOG.0000429658.85846.f9"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00404-017-4341-9"},{"issue":"2","key":"e_1_2_5_4_1","first-page":"121","article-title":"Growth restriction intervention trial","volume":"67","author":"When do obstetricians recommend delivery for a high\u2010risk preterm growth\u2010retarded fetus?
