We are concerned that their analysis in cluded deaths early and late in the season that w...
متن کاملSensitivity analysis for interactions under unmeasured confounding.
We develop a sensitivity analysis technique to assess the sensitivity of interaction analyses to unmeasured confounding. We give bias formulas for sensitivity analysis for interaction under unmeasured confounding on both additive and multiplicative scales. We provide simplified formulas in the case in which either one of the two factors does not interact with the unmeasured confounder in its ef...
متن کاملCost effectiveness of influenza vaccination for specific populations in Iran
Introduction: Influenza viruses are the major respiratory pathogens worldwide and high-risk groups such as healthcare workers may develop severe forms of the disease. The purpose of this study was to evaluate the cost-effectiveness of influenza vaccination for 4 target groups including pregnant women, elderly people (aged over 65 years), healthcare workers and school-age children in Iran.

متن کاملApplication of the case-crossover design to reduce unmeasured confounding in studies of condom effectiveness.
This analysis examined how unmeasured confounding affects estimates of the effectiveness of condoms in preventing sexually transmitted infections. Data were analyzed from a prospective cohort study of 1,122 female sexually transmitted disease clinic patients in Alabama (1992-1995), wherein participants were evaluated for sexually transmitted infections at six 1-month intervals. Associations bet...
متن کاملSharp sensitivity bounds for mediation under unmeasured mediator-outcome confounding
It is often of interest to decompose the total effect of an exposure into a component that acts on the outcome through some mediator and a component that acts independently through other pathways. Said another way, we are interested in the direct and indirect effects of the exposure on the outcome. Even if the exposure is randomly assigned, it is often infeasible to randomize the mediator, leav...
