14 August 2013	New citation required and conclusions have changed	With the addition of one new trial of vaginal PGE2, there is now no evidence of a difference between the likelihood of women requiring instrumental delivery in either setting. In the previous version of this review, women in the outpatient group were more likely to have instrumental deliveries.
30 June 2013	New search has been performed	Search updated. Eight new trial reports identified. One new trial (five reports) included (Wilkinson 2015 ‐ OPRA) and one trial (three reports) excluded (Henry 2011). We have also excluded a trial previously awaiting classification (Rijnders 2011) and moved one previously ongoing study report ‐ Turnbull 2009 ‐ to the included section under Wilkinson 2015 ‐ OPRA .
