The prevalence of type 2 diabetes in South Africa : a systematic review protocol
(BMJ Publishing Group, 2018-06)Introduction Type 2 diabetes mellitus is a major source of morbidity and mortality in South Africa, spurred by increased urbanisation and unhealthy lifestyle factors. Local epidemiological data are required to inform ... -
A taxonomically and geographically constrained information base limits non-native reptile and amphibian risk assessment : a systematic review
(PeerJ, 2018)For many taxa, new records of non-native introductions globally occur at a near exponential rate. We undertook a systematic review of peer-reviewed publications on non-native herpetofauna, to assess the information base ... -
Treatment interventions for diarrhoea in HIV-infected and HIV-exposed children : a systematic review
(African Field Epidemiology Network, 2018)Introduction: seventy percent of an estimated 10 million children less than five years of age in developing countries die each year of acute respiratory infections, diarrhoea, measles, malaria, malnutrition or a combination ... -
