The study aimed to create reference charts for measuring fetal growth in Karachi, Pakistan, involving 1228 women with singleton pregnancies.
Key fetal measurements like biparietal diameter, head circumference, abdominal circumference, and femur length were taken repeatedly until delivery and analyzed using regression techniques.
The resulting percentiles for these measurements are the first ever in Karachi, aiding in the diagnosis of fetal growth issues and laying groundwork for national growth charts.
