POC-CCA, point-of-care immunodiagnostic for detecting schistosome cathodic circulating antigen; epg, egg per gram.
(a,b) Different letters in the same line indicate a significant difference between the two means at 0.05 level of significance by using t-test (equal variances not assumed).
(A, B) Different letters in the same column indicate a significant difference between the means at 0.05 level by using post-hoc Tukey’s test.
