Date	Event	Description
7 January 2021	Amended	Edited Abstract/Main results to remove superflous 'we' from the text.
19 December 2020	Feedback has been incorporated	The authors have responded to Feedback 8.
3 September 2020	New citation required and conclusions have changed	Overall, the conclusions remain the same. However with the addition of additional studies from low‐ and medium‐resource settings the conclusions are more certain for perinatal mortality, and for neonatal mortality and morbidity. This new evidence has been reflected in the conclusions.
3 September 2020	New search has been performed	Search updated and three recently‐published studies added as well as two studies added that were excluded from the previous version of the review. Six studies included in the previous version did not meet Pregnancy and Childbirth trustworthiness criteria and have not been included in this update.

The review now includes a total of 30 studies. The conclusions remain unchanged.

14 March 2007	Feedback has been incorporated	Feedback from David Hutchon added.
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 2002a; 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.
