KE/FK/0757/EC/2018). All methods were performed in accordance with the relevant guidelines and regulations.

For those who were interviewed by phone call, we recorded their oral consent. Except for telephone interviews, all sessions were conducted in private rooms, and participants were given the opportunity to ask questions about the study. For the secondary data, permissions were obtained from each institution in selected provinces. We ensured that individual participants were anonymized in the written reports and publications.
