The effect of customization and use of a fetal growth  standard on the association between birthweight percentile and adverse perinatal outcome: methodologic issues

I was interested to read the study by Sovio and Smith1 that was published in the valuable journal of American Journal of Obstetrics and Gynecology. They identified an independent association between birthweight percentile and adverse outcome, namely, maternal preeclampsia, perinatal death, or morbidity. This is an interesting finding; however, some methodologic issues should be taken into consideration to avoid misinterpretation.
