23 May 2007	New search has been performed	Search updated on 28 February 2007. The current update includes 14 new trials bringing the total to 46 trials. The review now includes more evidence on misoprostol compared to placebo at non‐hospital, peripheral settings. The conclusions related to misoprostol comparison to conventional injectable uterotonics and that of intramuscular prostaglandins remain unchanged. Three papers from China are in the awaiting assessment section pending their translation.
23 May 2007	New citation required but conclusions have not changed	The statistics editor noticed some discrepancies in standard deviation figures of continuous data in some trials. In Switzerland 1999 the data were actually reported as standard error and this has been corrected. Continuous data from India 1988c, Nigeria 2003 and Ghana 2000 have ben excluded because they could not be reconciled by looking at the paper again.
21 November 2003	New search has been performed	The current update includes 5104 additional women from seven misoprostol trials (Canada 2002; Colombia 2002; France 2001; Nigeria 2003; Turkey 2002; Turkey 2003; United Kingdom 2003) and some excluded trials. The conclusions of the review have not changed.
