Clinical features and settings Presenting signs and symptoms: Fever
Previous treatment for malaria: No information presented on previous treatment; no suggestion of any exclusions based on previous treatment
Clinical setting: Malaria clinics
Country: India (Assam)
Malaria endemicity: Mesendemic
Malaria endemic species:P. falciparum and P. vivax
Participants Sample size: 336; but varied by RDT evaluated (10 to 139)
Age: Infants under 12 months excluded; actual age range 1 to 60 years
Sex: Both males and females eligible. Actual proportions of males and females in the participant population not stated.
Co‐morbidities and pregnancy: No exclusion criteria based on co‐morbidities or pregnancy were stated, and no details of the frequency of these conditions in the participant population is presented
Parasite density of microscopy positive cases: Range 300 to 350,000 parasites per μl, mean 59,842, Standard Deviation 78,780
Study design Enrollment was prospective. The sampling method was not described. Seven RDTs were evaluated; it is unclear how each RDT was allocated, as no participant received all the tests.
Target condition and reference standard(s) Target condition: Malaria parasitaemia
Reference standard: Microscopy thick and thin blood smears
Person(s) performing microscopy: Technician; all positive slides and 20% of negative slides were also examined by the senior technician for confirmation of result.
Microscopy setting: Laboratory at the malaria clinics
Number of high power fields examined before declaring negative: 100
Number of observer or repeats: One in the case of most smears judged negative by the technician. Two in the case of 20% of those initially judged negative, and all those judged positive.
Resolution of discrepancies between observers: The judgement of the senior technician was used

Table of Methodological Quality
Item Authors' judgement Description
Representative spectrum? 
 All tests Unclear All participants were attending malaria clinics with fever. However, during the study period, 6663 blood smears were examined, but only 336 were evaluated with RDT kits, and the sampling method for RDT evaluation was unclear.
Acceptable reference standard? 
 All tests Unclear Two observers were used in the vast majority of cases; however, it is unclear whether the observers worked independently
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 and RDT results were compared by an independent observer
Index test results blinded? 
 All tests Yes Microscopy and RDT results were compared by an independent observer
Uninterpretable results reported? 
 All tests Unclear No information presented on numbers initially allocated each RDT, so not possible to judge this
Withdrawals explained? 
 All tests Unclear No information presented on numbers initially allocated each RDT, so not possible to judge this
