Additional author: During the editing process of the article “Induction of labour with a Foley catheter or oral misoprostol at term: the PROBAAT-II study, a multicentre randomised controlled trial“ [1] an author has been accidentally removed from the author list. Gert J van Baaren (Department of Obstetrics and Gynecology, Academic Medical Centre, Amsterdam, the Netherlands, g.j.vanbaaren@amc.uva.nl) critically revised the first draft, and approved the final version of the manuscript. He was especially involved in the sections relating to the cost-effectiveness analysis.
