Main characteristics of subjects with inapparent dengue infections compared to non-dengue-infected subjects among Household members.

<p>*Potential confounders with a P value of less than 0.20 in univariate analysis were retained for the final multivariable analyses. In this table: age, platelets, neutrophils, lymphocytes, ASAT and IgG at Visit 1.</p>a<p>ASAT: Aspartate amino transferase.</p>b<p>ALAT: Alanine amino transferase.</p><p>Univariate and multivariable logistic regression were used for analyses.</p

Characteristics of dengue index cases (DIC, n = 215).

<p>*For 3 subjects infected by DENV-2, data related to IgG status were missing: 2 dengue fever cases and 1 severe dengue case.</p><p>Distribution of DIC is provided by region in relation to the presence of WHO criteria for severe dengue and IgG status during the acute phase.</p

Localization of the four clinical sites.

<p>A: in South-East Asia (Cambodia and Vietnam). B in Latin America (Brazil and French Guiana).</p

Main characteristics of subjects with inapparent dengue infections compared to symptomatic dengue-infected subjects.

<p>*Potential confounders with a P value of less than 0.20 in univariate analysis were retained for the final multivariable analyses. In this table: weight-based Z-score, platelets, neutrophils, lymphocytes, monocytes, ASAT, ALAT and NS1 antigen.</p>a<p>ASAT: Aspartate amino transferase.</p>b<p>ALAT: Alanine amino transferase.</p><p>Univariate and multivariable logistic regression were used for analyses.</p

Study design for the inclusion of patients.

<p>A: Step 1, identification of dengue index cases (DIC) and non-dengue-infected cases (NDC). B: Step 2, Identification of household members (HHM).</p

Distribution of the participants in the clinical study (n = 590).

<p>All participants were identified at Visit 1 for Dengue Index Cases (DIC) and at Home Visit 1 for dengue-infected household members (HHM). Their distribution is presented by country, according to DENV-infected status and IgG status.</p
