SDC1 and preeclampsia: Despite one high value outlier (2237 ng/mL), soluble Sdc1 levels in this SGA-preeclampsia sub-group were significantly lower than controls [median pg/mL (range): 225 (101–2237); P < 0.01]; these SGA-preeclampsia values, at gestational age 31 (range 26–33) weeks, were comparable to those observed at 7–11 weeks of uncomplicated pregnancy (Fig 1).
