Competing Interests

Tin Aung and Thin Myat Khine work for PSI/Myanmar, an NGO supporting the provision of medical care in Myanmar using private sector channels. PSI/Myanmar provided direct and indirect support for this study using funds from external donors. The employment of two authors by PSI/Myanmar does not alter the authors' adherence to all the PLoS ONE policies on sharing data and materials.
