^aAUC, area under curve;

^bLikelihood ratio represents the likelihood that someone with a positive test will live in a BU endemic area, i.e. a likelihood ratio of 5.0 means someone with a positive test is 5 times more likely live in BU endemic area than an individual with a negative test;

^cNPV, negative predictive value.
