Performance of computerized cardiotocography-based short-term variation in late-onset small-for-gestational-age fetuses and reference ranges for the late third trimester.

We report no significant difference in STV median values between controls, SGA and FGR pregnancies. However, more SGA fetuses had a low STV compared to controls. Prospective longitudinal studies are needed to investigate if low STV is a useful surveillance method for late-onset FGR.
