  2. aStandard care and supportive care include any of intravenous fluids, antimicrobial and anti-malarial treatment, electrolyte replacement, medications for symptomatic management, nutritional support, laboratory tests, and hemodynamic monitoring. Medications, laboratory tests, and frequency of hemodynamic monitoring varied among each respective treatment centre
  3. bThis study uses the term ‘historical controls’, but reports that 21 of the 38 controls were recruited at the same time and in the same centre as patients in the intervention arm [27]. The remaining 17 controls were treated in other centres in Guinea. We therefore classified the study as using concurrent controls
  4. cThis study presents data on mortality in historical controls in an appendix and used these data to calculate the sample size
