All data are from the first day stool and urine specimens. Columns show positive and negative polymerase chain reaction (PCR) results for four subgroups defined by the subject's Kato-Katz and point-of-care assays for parasite circulating cathodic antigen (POC/CCA) test results. Numbers in parentheses indicate row percentages.
