IFC was defined as the presence of persistent pathological cardiotocography pattern or the combination of pathological cardiotocography pattern and fetal scalp pH\u00a0&lt;\u00a07.20. Operative delivery included instrumental vaginal delivery and cesarean section. Pregnancies were grouped according to birthweight (small for gestational age [SGA, birthweight &lt;10th centile] and appropriate for gestational age [AGA, birthweight 10th\u201390th centile]) and gestational age by week at delivery.

Overall, the rates of operative delivery for IFC were higher in the low CPR group both in SGA (35% vs. 22%; <jats:italic>p<\/jats:italic>\u00a0=\u00a00.023) and in AGA (23% vs. 16%; <jats:italic>p<\/jats:italic>\u00a0=\u00a00.007). According to gestational age by week at delivery, fetuses with low CPR showed higher rates of operative delivery for IFC with advancing gestational age, mainly in pregnancies delivered at 40\u00a0weeks (54% vs. 23%; <jats:italic>p<\/jats:italic>\u00a0=\u00a00.004) and at 41\u00a0weeks (60% vs. 19%; <jats:italic>p<\/jats:italic>\u00a0=\u00a00.010) for SGA and at 41\u00a0weeks (39% vs. 20%; <jats:italic>p<\/jats:italic>\u00a0=\u00a00.001) for AGA.
