Patient characteristics and setting Species: S. mansoni
Country: Cameroon
Sample size: 138
Age range: 7 to 15 years
Participants: children who provided all 3 samples
Setting: field study (low endemicity)

Flow and timing  
Comparative  
Notes This article describes part of a multi‐centre study (Colley 2013), which was similar to Tchuente 2012_9KK, but in this article, 2‐by‐2 tables of the CCA POC measured against the first daily stool specimen (triplicate KK smears on 1 stool sample) were presented

If a threshold was used, was it pre‐specified? Yes    
Was quality control done? Yes    
    Unclear Low
DOMAIN 3: Reference Standard
Is the reference standards likely to correctly classify the target condition? Yes    
Were the reference standard results interpreted without knowledge of the results of the index tests? Unclear    
Was quality control done? Unclear    
    Unclear Low
DOMAIN 4: Flow and Timing
Was there an appropriate interval between index test and reference standard? Yes    
Did all patients receive the same reference standard? Yes
