Table of Methodological Quality
Item Authors' judgement Description
Representative spectrum? 
 All tests Yes Participants were a consecutive series who had a fever and were seeking treatment for suspected malaria
Acceptable reference standard? 
 All tests No An experienced microscopist viewed at least 200 high power fields before declaring a slide negative; however their results were not verified by a second, independent reader
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 "The blood smears were examined by experienced microscopists who were unaware which samples had been found positive in the RDT and which negative"
Index test results blinded? 
 All tests Yes Local team member read the results independently and without knowledge of the microscopy results
Uninterpretable results reported? 
 All tests Unclear The numbers of participants originally enrolled in the study was not clearly stated, therefore it is unclear whether there were any exclusions due to invalid test results
Withdrawals explained? 
 All tests Unclear The numbers of participants originally enrolled in the study was not clearly stated, therefore it is unclear whether there were any withdrawals
