Abbreviations: AGP, alpha-1 acid glycoprotein; CI, confidence interval; DENV, dengue virus; OFI, other febrile illness; OR, odds ratio; RBP, retinol-binding protein.
a P values obtained using a Wald χ 2 tests for independence.
b P values obtained from polytomous logistic regression, Type 3 analysis of effects. Each illness category compared to“healthy control” as the reference group. Model is adjusted for age, sex, and body mass index.
cAdjusted for acute-phase response using the Thurnham correction factor.
dAGP modeled as value per 0.1 g/L.
