Figure 4.

Ratio of PGE2 to PGE2-EA and PGF2a to PGF2a-EA in the study groups. Women who had an episode of preterm labor (PTL) were divided into four groups: (1) term delivery (PTL-TD); (2) preterm delivery without intra-amniotic inflammation (PTL-PTD NI); (3) preterm delivery with sterile intra-amniotic inflammation (PTL-PTD SIAI); and (4) preterm delivery with intra-amniotic infection (PTL-PTD IAI).
