n denotes the number of studies that measured the prostaglandin/metabolite. Abbreviations: AF = amniotic fluid, PL = plasma, UR = urine, SE = serum, COX 1/2 = cyclooxygenase 1/2, PGFM = 13,14-dihydro-15-keto-PGF2α, PGEM = 13,14-dihydro-15-keto-PGE2, bicyclo-PGEM = 11-deoxy-13,14-dihydro-15-keto-11,16-bicyclo PGE2, t-PGFM = 5α,7α-dihydroxy-11-keto tetranor-prostane-1,16-dioic acid.
