The levels of pregnancy-associated plasma protein A (PAPP-A) and \u03b2-human-derived chorionic gonadotrophic (\u03b2-hCG) in the first trimester can predict this adverse outcome, considering the controversial nature of studies in this area, this cohort study was conducted to investigate the role of PAPP-A and free\u03b2-hCG levels for predicting SGA.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials and Methods:<\/jats:title>\n                    <jats:p>In this cohort study, from 16 randomly selected health centers in Isfahan, Iran, 4605 volunteer pregnant women who had performed first-trimester fetal anomalies screening tests were chosen based on the census, from July 2016 to June 2018. The multiples of the median (MoM) PAPP-A &lt;0.4 and MoM \u03b2-hCG &gt;3 were considered as abnormal; the samples were followed up after childbirth. The biomarkers' serum levels, relative risk, and odds ratio (OR) of SGA were compared in both SGA and appropriate for gestational age (AGA) groups.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      In the SGA group, the mean of MOM PAPP-A was significantly lower (0.96 vs. 1.1 with\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 0.001) and MoM \u03b2hCG was significantly higher (1.24 vs. 1.15 with\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 0.01) than the AGA group.
