Ethics approval and consent to participate
: Ethical approval was obtained from Nigerian Health Research Ethics Committee with approval number NHREC/ 01/01/2007–16/11/2015b on 16th November 2015 and the Johns Hopkins School of Public Health, IRB #000007196, on August 23rd, 2016. The trial was retrospectively registered with the NIH-Sponsored ClinicalTrials.Gov registry on 24th August, 2017: NCT03269240. Verbal informed consent was obtained from study participants and confidentiality was assured. Verbal informed consent was used because the authors thought that asking health providers to review and sign forms might be considered risky because of the fear that if they performed poorly their supervisors may see their scores and trace it back to them.
