Competing Interests

I have read the journal's policy and have the following conflicts: The authors are engaged in a large project that is testing a model to increase access to injectable contraceptives at the community level that requires payment from clients. This does not alter the authors' adherence to all the PLOS ONE policies on sharing data and materials, as detailed online in the guide for authors.
