 The more recent publication from Caughey and Parer examined the literature for evidence regarding a dose response of the benefits and detriments of antenatal corticosteroids. Based on their complex mathematical analysis they recommend all fetus between 24 and 34 weeks gestation at risk for preterm delivery should be given a first course of ANC. If the risk of preterm delivery persists the next course should be given 2 weeks later, for a maximum of two courses. Consistent with all previous articles, the call for a well designed randomized, controlled trial is made.
