Posterior probabilities of vector infection (or non-infection) with Trypanosoma cruzi, given test results: positive and negative predictive values. EPRS, entomological-parasitological routine surveillance; UnB, University of Brasília; cPCR, conventional PCR on the 24Sα subunit of the nuclear ribosomal DNA; qPCR, quantitative PCR on the nuclear satellite DNA. Note that positive predictive values of cPCR (black line) and qPCR (green broken line) largely overlap.
