Ethical considerations and funding
Data were collected retrospectively and recorded and stored in an
anonymized form without patient or provider identifiable information.
This research fulfilled the exemption criteria set by the MSF’s Ethics
Review Board for a posteriori analyses of routinely collected clinical
data and thus did not require MSF ERB review. There was no functioning
ethics review board in Yemen, and the study was conducted with
permission from the Medical Director of MSF’s Operational Centre in
Amsterdam. The protocol was registered at clinicaltrials.gov and MSF
supported data collection, analysis and publication, with no relation to
industry or multi- or bilateral agencies.
