CONSORT flow diagram.
HC means health centre, S.D. means standard deviation; *Information about the existence of both MAM and SAM services was initially obtained from the Ministry of Health; once the randomization was performed, while gathering more information from each HC, we realised than nine of them did not provide either the MAM (one) or the SAM (eight) services. Providing both services was an inclusion criterion, so these nine HC were removed from the list. Source: authors.
