Adjusted odds ratios for mortality and ICU admission in Mexico (A), Brazil (B), and Colombia (C). NC = noncalculable. Risk factors included in the multivariate logistic regression models were comorbidities identified in the univariate analysis in at least two age groups in at least two databases. Infectious diseases were excluded to prevent potential confounding effects because of the presence of differential diagnoses for dengue/other infections in this category. Dengue severity, age, and year of admission were also included in the models.
