The smallest babies at every gestational age suffer the highest mortality [
1]. This risk is attributed to fetal growth restriction (FGR, formerly known as intrauterine growth restriction or IUGR). Fetal growth restriction is commonly defined as a failure of the fetus to reach its hypothetical growth potential [
2]. A major challenge to the study of FGR is its lack of a gold-standard definition. An infant’s size is easily measured but its growth potential is not. There are clinical signs that may accompany a fetus’ failure to reach its potential size, for example reduced fetal arterial blood flow before birth [
3] and placental abnormalities [
4] or physical wasting after birth [
5]. However, none of these signs is pathognomonic—all lack sensitivity and specificity. …
