Search strategy
A systematic review was conducted in MEDLINE, EMBASE and Cochrane
databases using a combination of Medical Subject Headings (MeSH) and
free text as follows:
antenatal corticosteroid OR antenatal glucocorticoid OR antenatal
steroid OR prenatal steroid OR dexamethasone OR betamethasone
AND
cardiovascular OR heart OR echocardiography OR blood pressure
Subsequently, a grey literature (first 100 hits in Google Scholar and
Pubmed) search was performed, and reference lists of relevant review
articles were manually checked. Forward citation searching was also
performed, whereby key papers identified were located in Web of Science
to identify other work where they may have subsequently been cited;
references of these papers were also checked. Covidence software
(Veritas Health Innovation Ltd, Melbourne, Australia) was used to
eliminate duplicate articles and manage study screening.
