Two reviewers measured the fetal thigh STT on saved images. The estimated gestational age, fetal biometric measurements, and ABW were abstracted.

Seventeen (21%) fetuses were small for gestational age at birth. The Hadlock formula underestimated the EFW relative to the ABW, with an average difference of \u221297\u2009g (\u22123.9%) and\u2009\u2212\u20095.1% in terms of growth percentiles. All of the STT\u2010based EFW formulas overestimated the EFW on average by 327 to 701\u2009g (13%\u201324%) in terms of weight and 26% to 52% in terms of growth percentiles. The Hadlock formula classified 22 as having intrauterine growth restriction (sensitivity, 65%; specificity, 83%, based on the ABW).
