Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	Random numbers used.
Allocation concealment (selection bias)	Low risk	"Each child was then assigned a random number from a list prepared by an independent collaborator and thus allocated at random to receive either intramuscular artemether or intravenous quinine".
Blinding (performance bias and detection bias) Objective outcome: Death	Low risk	An open‐label trial is unlikely to bias an objective outcome like death.
Blinding (performance bias and detection bias) Subjective outcomes: Others	High risk	"This was a randomized, open, controlled study in which no attempt was made to ‘blind’ the investigators, as the test drug and the control drug were given by 2 different routes".
Incomplete outcome data (attrition bias) All outcomes	Low risk	Only 1 patient excluded from fever clearance time outcome assessment because of urinary tract infection.
Selective reporting (reporting bias)	Low risk	No evidence of selective reporting.
Other bias	Low risk	No other bias identified.
