The diagnostic performance of the POC-CCA assay for human schistosomiasis japonica using concentrated urine samples. A Healthy control group (n = 15) and KK-positives with an EPG ≥ 10 (n = 30) were tested by the POC-CCA assay; B Healthy controls (n = 15) and all KK-positives (n = 108) were tested by the POC-CCA assay. P values were determined using the Mann–Whitney U test (ns = no significant difference); C, D ROC curve analysis for the POC-CCA assay was performed to evaluate its capability in discriminating the healthy control group and KK-positives with EPG ≥ 10 (n = 30) (C) and all KK-positives (n = 108) (D).
