Query: Sensitivity analysis for unobserved confounding of direct and indirect
  effects using uncertainty intervals   To estimate direct and indirect effects of an exposure on an outcome from
observed data strong assumptions about unconfoundedness are required. Since
these assumptions cannot be tested using the observed data, a mediation
analysis should always be accompanied by a sensitivity analysis of the
resulting estimates. In this article we propose a sensitivity analysis method
for parametric estimation of direct and indirect effects when the exposure,
mediator and outcome are all binary. The sensitivity parameters consist of the
correlation between the error terms of the mediator and outcome models, the
correlation between the error terms of the mediator model and the model for the
exposure assignment mechanism, and the correlation between the error terms of
the exposure assignment and outcome models. These correlations are incorporated
into the estimation of the model parameters and identification sets are then
obtained for the direct and indirect effects for a range of plausible
correlation values. We take the sampling variability into account through the
construction of uncertainty intervals. The proposed method is able to assess
sensitivity to both mediator-outcome confounding and confounding involving the
exposure. To illustrate the method we apply it to a mediation study based on
data from the Swedish Stroke Register (Riksstroke).
