Table of Methodological Quality
Item	Authors' judgement	Description
Representative spectrum? All tests	Unclear	All participants were attending malaria clinics with fever, but the sampling method was not described
Acceptable reference standard? All tests	Unclear	Microscopy was undertaken by experts at a central laboratory, but there were no details provided about the processes used
Partial verification avoided? All tests	Yes	All participants who received the index test also received the reference test
Differential verification avoided? All tests	Yes	The same reference test was used regardless of the index test results
Incorporation avoided? All tests	Yes	The index test does not form part of the reference standard
Reference standard results blinded? All tests	Yes	Microscopy was undertaken at a different location than the RDTs
Index test results blinded? All tests	Yes	RDTs were undertaken at a different location than the microscopy
Uninterpretable results reported? All tests	Unclear	Number of participants enrolled in the study was explicitly stated and corresponded to the number presented in the analysis; therefore there were no withdrawals due to invalid results
Withdrawals explained? All tests	Yes	Number of participants enrolled in the study was explicitly stated and corresponded to the number presented in the analysis; therefore there were no withdrawals
