At the time of the survey she was employed by MSD Sweden as medical advisor for products within reproductive health. The survey was fully sponsored by MSD Sweden but HKK, LT, JB and KGD received no compensation for manuscript writing. Kristina Gemzell Danielsson is associate editor of PLOS ONE. This does not alter the authors' adherence to PLOS ONE editorial policies and criteria.
