Combined and individual analyses of each center revealed no significant difference in fetal intolerance of labor (<jats:italic>P<\/jats:italic> = .19) or cesarean delivery for fetal intolerance (<jats:italic>P<\/jats:italic> = .074) between cohorts. In both settings, patients with a borderline AFI were more likely than those with a normal AFI to undergo antepartum testing (<jats:italic>P<\/jats:italic> &lt; .001). A statistically significant increase in intrauterine growth restriction in the borderline AFI group was noted, with a calculated risk ratio of 13.76 (<jats:italic>P<\/jats:italic> &lt; .001). There was no difference between groups for meconium\u2010stained amniotic fluid (<jats:italic>P<\/jats:italic> = .23), neonatal intensive care unit admission (<jats:italic>P<\/jats:italic> = .054), preterm delivery (<jats:italic>P<\/jats:italic> = .31), or operative vaginal delivery (<jats:italic>P<\/jats:italic> = .45).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The findings of this study suggest that there is no difference in the rate of fetal intolerance of labor in pregnancies with a borderline AFI and those with a normal AFI. Pregnancies complicated by a borderline AFI are more likely to undergo antepartum testing, yet the benefit is unclear. Significantly more patients with a borderline AFI had underlying growth restriction, which may provide a useful tool for risk stratification in the management of a borderline AFI.<\/jats:p><\/jats:sec>","DOI":"10.7863\/ultra.33.4.705","type":"journal-article","created":{"date-parts":[[2014,3,21]],"date-time":"2014-03-21T21:46:53Z","timestamp":1395438413000},"page":"705-711","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Borderline Amniotic Fluid Index and Its Relation to Fetal Intolerance of Labor"],"prefix":"10.1002","volume":"33","author":[{"given":"S.
