| Overall | Healthy Control | Nonfebrile DENV | OFI | Apparent DENV | |||||
|---|---|---|---|---|---|---|---|---|---|

Abbreviations: CI, confidence interval; DENV, dengue virus; IL, interleukin; MFI, median fluorescence intensity; OFI, other febrile illness; OR, odds ratio.
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.
