  1. All-inclusive, additive logistic regression models to evaluate the contribution of demographic and hematological factors to DENV incidence using different datasets (ALL = entire data; subsets s1 to s4 ordered by day of the first attendance at the Marilia Hemocenter; see text). AIC indicate model fit (comparable only between subsets s1 to s4). βo = intercept, β1 = slope, OR = odds ratio, and CL = 95 % confidence limits. Figures lower than critical P were in bold. Considering five models (one for each dataset), critical P = 0.05/5 = 0.01. Variable codes as in Table 1
