Multivariable logistic regression analysis was used to determine whether the addition of maternal serum PlGF improved the performance of screening that was achieved by a combination of maternal factors and PAPP\u2010A, DV\u2010PIV and UtA\u2010PI.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Significant contribution to the prediction of stillbirth was provided by maternal factor\u2010derived <jats:italic>a\u2010priori<\/jats:italic> risk and multiples of the median values of PlGF, DV\u2010PIV and UtA\u2010PI but not of serum PAPP\u2010A. A model combining these variables predicted 42% of all stillbirths and 61% of those due to impaired placentation, at a false\u2010positive rate of 10%; within the impaired placentation group the detection rate of stillbirth &lt; 32 weeks' gestation was higher than that of stillbirth \u2265 37 weeks (71% <jats:italic>vs<\/jats:italic> 46%; <jats:italic>P<\/jats:italic> = 0.031).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>A high proportion of stillbirths due to impaired placentation can be identified effectively in the first trimester of pregnancy.
