Figure 2. Amniotic fluid concentration of esRAGE in normal pregnancies at mid-trimester and in those at term with and without labor.
Patients at term not in labor had a higher median amniotic fluid concentration of esRAGE (median: 8,520 pg/ml, range: 0–22,628) than those in the mid-trimester (median: 59.5 pg/ml, range: 0–699; p<0.001) and those at term in labor (median: 6,056 pg/ml, range: 0–15,073; p=0.04). The logarithmic scale was used to better visualize the midtrimester values.
