Participants |
Sample size: 328 Age: All ages above five years eligible; mean age 28.3 years (range 5 to 72 years) Sex: Both males and females eligible; 64% of the participants were males Co‐morbidities and pregnancy: No exclusion criteria based on co‐morbidities or pregnancy.

Item | Authors' judgement | Description |
Representative spectrum? All tests | Yes | Participants were a consecutive sample of people attending clinics with fever or history of fever |
Acceptable reference standard? All tests | Yes | Twp independent trained microscopists viewed 400 high power fields before declaring a slide negative |
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 | Unclear | Blinding not described |
Index test results blinded? All tests | Unclear | Blinding not described |
Uninterpretable results reported? All tests | Unclear | The number of participants enrolled was clearly stated, and the number included in the analysis corresponds to this number, indicating no withdrawals |
Withdrawals explained? All tests | Yes | The number of participants enrolled was clearly stated, and the number included in the analysis corresponds to this number, indicating no withdrawals |
