Ultrasound biometric parameters\u2014biparietal diameter, head circumference, abdominal circumference, and femur length\u2014were used to estimate fetal weight via the Hadlock\u20103 formula. EFW percentiles were calculated using both the WHO fetal growth standards and the Thai fetal growth chart. The proportions of fetuses classified as SGA (&lt;\u200910th percentile) and LGA (&gt;\u200990th percentile) were compared.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The WHO chart classified a significantly higher proportion of fetuses as SGA (27.1%) compared to the Thai chart (12.7%) (\n                      <jats:italic>p<\/jats:italic>\n                      &lt; 0.001), while identifying fewer fetuses as LGA (3.3% vs. 5.4%,\n                      <jats:italic>p<\/jats:italic>\n                      &lt; 0.001).
