Intersection of results from three tests for Plasmodium parasitaemia in asymptomatic children. Upset plot of the overlap of participants testing positive by microscopy, us-RDT, and qPCR for enrollment (A) and follow-up at 6–10 weeks (B). The number of participants with each test result is presented as the set size. Connecting dots indicate the combination of test results, which are plotted by increasing count frequency. Red connections highlight qPCR positive samples detected by us-RDT but missed by microscopy
