Table 3 Summary statistics and prevalence by different diagnostic tests in eight schools in Burundi. Samples from each child were tested using four different diagnostics: Kato-Katz performed in Burundi, CCA performed in Burundi, CCA performed in Leiden and CAA performed in Leiden. Additionally, CCA results were considered both with trace results as negative and with trace results positive

From: Latent class analysis to evaluate performance of point-of-care CCA for low-intensity Schistosoma mansoni infections in Burundi

CCA in Burundi: trace-positive (CCABtp) 53.5 (12.0–90.0)
CCA in Leiden: trace-negative (CCALtn) 28.4 (0.0–60.0)
