Table 2.
Baseline proportion of infected children and intensities of 404 investigated children by six Kato-Katz smears, three POC-CCA tests and gold standard. Gold standard is the combined results of six Kato-Katz smears and three POC-CCAs. The proportion by POC-CCA tests is calculated considering trace as positive (t +). 95% CI = 95% confidence interval, n.a = not applicable.
