Item Authors' judgement Description
Representative spectrum? 
 All tests Yes Participants were a consecutive sample of people presenting at healthcare facilities with clinically suspected malaria
Acceptable reference standard? 
 All tests Unclear Unclear how many observer repeats were used, but the microscopy was described as the 'gold standard'
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 Reported that the tests were performed blindly
Index test results blinded? 
 All tests Yes Reported that the tests were performed blindly
Uninterpretable results reported? 
 All tests Unclear Number enrolled in the study was explicitly stated and corresponded to the number presented in the analysis; therefore no withdrawals due to invalid results
Withdrawals explained? 
 All tests Yes Number enrolled in the study was explicitly stated and corresponded to the number presented in the analysis; therefore no withdrawals
