30 October 2005	New search has been performed	The review substantially updates the Crowley 2006 review due to new Cochrane guidelines for inclusion and exclusion of studies and the need for the review to be standardised with the repeat courses of prenatal corticosteroids review. Six new trials have been included (Amorim 1999; Dexiprom 1999; Fekih 2002; Lewis 1996; Nelson 1985; Qublan 2001). Three studies that were included in the previous review have been excluded. The results are now presented as relative risks. Results from recent follow‐up studies have been included. Individual participant data were available from the Liggins and Howie study and these were analysed completely by intention‐to‐treat analysis for the first time. These data contribute nearly a third of the data to the review. This represents an important development. The review also provides new information on corticosteroid use in the presence of rupture of membranes, hypertension syndromes, in multiple pregnancies and according to gestational age at first corticosteroid dose.
