Estimates of effect of significant domicile construction materials on Triatoma dimidiata intradomiciliary prevalence >5%.

Univariate logistic regression models were developed to investigate the effect of each domicile construction material on Triatoma dimidiata intradomiciliary village prevalence >5% by survey and department. Odds ratios (OR) and 95% confidence intervals for significant risk factors are reported. Domicile construction risk factors represent the proportion of domiciles per village constructed with each material as determined by the 2002 national census of the Guatemalan National Institute of Statistics [40].
