Combining rapid diagnostic tests to estimate primary and post-primary dengue immune status at the point of care
Fig 2
Estimated probability of being DENV RDT positive according to corresponding laboratory-derived metrics using logistic regression modelling.
A: IgM RDT positivity according to IgM panbio units and the corresponding sensitivity/specificity among patients from Indonesia (N:200) B: IgG RDT positivity according to IgG panbio units and the corresponding sensitivity/specificity among patients from Indonesia (N:200) C: NS1 RDT positivity according to viremia (Ct value) and the corresponding sensitivity/specificity stratified by disease day among patients from Vietnam (N: 1,217). Grey dash: estimated laboratory-derived metric threshold for RDT positivity according to the optimal Youden’s J index value.
