In the original publication  figures S1 and S2 should have been part of the main text rather than additional files.
There were some minor typographical errors on pages 2 and 4 and in the backmatter.
Page 2 should have read: ‘There is a clear knowledge gap with regard to effective strategies aimed at recruiters’ (, pg 1) and page 4: ‘After the review, an email is sent to all the collaborators at the site, summarising what was discussed at the review, providing attendance certificates and giving instructions for running the relevant bespoke stroke audit data exports.’
The backmatter: Trial status: The first recruitment review took place in September 2015, and the last review in August 2016. The first 6-month follow-up took place in March 2016, with the last one in February 2017.’
The original article has been updated to rectify these errors.
