Key Findings
The criteria by
Society
for Maternal and Fetal Medicine (SMFM) had higher sensitivity (40.82%
vs 24.49%, 20.41%) for small-for gestational age (SGA) compared to the
American College of Obstetrics and Gynecology (ACOG) and International
Society of Ultrasound in Obstetrics and Gynecology (ISUOG) criteria. On
the contrary, the ISUOG criteria had a higher specificity (99.18% vs
97.49%, 98.77%) than the SMFM and ACOG criteria for predicting SGA.
All three definitions had low sensitivity for ANO (17.32%, 12.6%,
11.81%) and high specificity of 95.8%, 97.88% and 98.51%. The AUCs
of SMFM for predicting SGA (0.692) and ANO (0.566) were slightly higher
than those of ACOG (0.616, 0.552) and ISUOG (0.598, 0.552).
