17 August 2017	Amended	This review has been amended since the last published version in April 2017. The overall conclusions remain unchanged. Two reports of a trial previously excluded have now been included (Cheyne 2008). This was a cluster‐randomised trial. The trial compared women attending units where assessment by midwives was carried out either using strict criteria for labour diagnosis using an algorithm or by routine assessment to decide whether women were in labour.
