Baseline maternal and demographic characteristics are presented in Table S2
Of the 1817 study subjects, the majority were young and primigravida, with on average education up to middle school level. Overall ,fetuses less ≤ 10th centile accounted for 18% (329/1817) of the antenatal scans. A total of 48.59%(883/1817) of fetuses were< 10th centile based on actual birthweight (Fenton chart). Further 33% (425/1817) had FGR and 25.26% (459/1817) had SGA on actual birth weight. Antenatal scans, therefore, detected approximately 28.1% of the fetuses at <10th percentile.
