Erratum

After publication of this work [1], we noted that we inadvertently failed to include the complete list of all coauthors and that sample sizes of some of the trials listed in Table two were incorrect.

The full list of authors has now been added and includes the names of all authors within the i-WIP Collaborative Network. The Authors’ contributions and competing interests section modified accordingly. We are publishing this erratum to update the author list, which is as follows:

Anneloes E Ruifrok, Ewelina Rogozinska, Mireille NM van Poppel, Girish Rayanagoudar, Sally Kerry, Christianne JM de Groot, SeonAe Yeo, Emma Molyneaux, Fionnuala McAuliffe, Lucilla Poston, Tracy Roberts, Richard D Riley, Arri Coomarasamy, Khalid Khan, Ben Willem Mol, Ruben Barakat Carballo, Maria Perales, Annick Bogaerts, Jose G Cecatti, Fernanda Surita, Jodie Dodd, Julie Owens, Nermeen El Beltagy, Roland Devlieger, Helena Teede, Cheryce Harrison, Lene Haakstad, Garry X Shen, Alexis Shub, Narges Motahari, Janette Khoury, Serena Tonstad, Riitta Luoto, Tarja I Kinnunen, Kym Guelfi, Fabio Facchinetti, Elisabetta Petrella, Suzanne Phelan, Tânia T Scudeller, Kathrin Rauh, Hans Hauner, Kristina Renault, Linda Reme Sagedal, Ingvild Vistad, Signe Nilssen Stafne, Siv Mørkved, Kjell Åsmund Salvesen, Christina Vinter, Marcia Vitolo, Arne Astrup, Nina Rica Wium Geiker and Shakila Thangaratinam.

The sample sizes of trials included in Table two have been corrected (Table 1). We are publishing this erratum to update these trial sample sizes, which include Dodd 2014 (n = 2212), Prevedel 2003 (n = 41), Renault 2013 (n = 425), Stafne 2012 (n = 855), Vinter 2011 (n = 360), Walsh 2012 (n = 800) and Wolff 2008 (n = 66).
