Data are n, sensitivity (95% credible interval), or specificity (95% credible interval). AWE=S mansoni adult worm extract. CAA=circulating anodic antigen serum and urine assay. CCA1=circulating cathodic antigen urine cassette assay version 1. CCA2=circulating cathodic antigen urine cassette assay version 2. LAMP=loop-mediated isothermal amplification. RDT=rapid diagnostic test. rtPCR=real-time PCR. SEA=S mansoni soluble egg antigen. SmCTF=S mansoni cercarial transformation fluid. SWAP=soluble adult worm antigen preparation.
Sensitivity and specificity were assumed constant across studies when the number of comparisons was less than four.
