Comparison of logistic regression models of neutralizing antibody titers to predict dengue PCR status.

a49 subjects (17 PCR positive, 32 PCR negative);b19 DENV-1 subjects (6 PCR positive, 13 PCR negative);c15 DENV-4 subjects (6 PCR positive, 9 PCR negative);d15 DENV-2 subjects (5 PCR positive, 10 PCR negative).PCR = polymerase chain reaction; PRNT = plaque reduction neutralization test; NT = neutralizing antibody titer; AIC = Akaike Information Criterion; AUC = area under receiver operating characteristic curve; CI = confidence interval; DENV = dengue virus; JEV = Japanese encephalitis virus.Models using neutralizing antibody titer alone and adjusted for age are shown.Comparison of logistic regression models of neutralizing antibody titers to predict dengue PCR status.
