Ethics approval and consent to participate
: All participants provided written informed consent. For those who were not able read or write, RA read them the consent forms, and explained the contents of the form. Illiterate individuals (those who could neither read nor write) would then use their thumbprints to sign on the consent forms. We used an inkpad to achieve this. Ethical clearance was obtained from the Makerere University, School of Medicine ethical review committee (SOMREC, Rec Ref# 2016–109) and Uganda National Council of Science and Technology (UNCST, HS20ES). Institutional permission to conduct the study was obtained from the St Francis of St Raphael Nsambya Hospital ethical committee. These approvals included the use of thumbprints as a means of providing informed consent for those who could neither read nor write.
