Query: Sensitivity Analysis for Multiple Comparisons in Matched Observational
  Studies through Quadratically Constrained Linear Programming   A sensitivity analysis in an observational study assesses the robustness of
significant findings to unmeasured confounding. While sensitivity analyses in
matched observational studies have been well addressed when there is a single
outcome variable, accounting for multiple comparisons through the existing
methods yields overly conservative results when there are multiple outcome
variables of interest. This stems from the fact that unmeasured confounding
cannot affect the probability of assignment to treatment differently depending
on the outcome being analyzed. Existing methods allow this to occur by
combining the results of individual sensitivity analyses to assess whether at
least one hypothesis is significant, which in turn results in an overly
pessimistic assessment of a study's sensitivity to unobserved biases. By
solving a quadratically constrained linear program, we are able to perform a
sensitivity analysis while enforcing that unmeasured confounding must have the
same impact on the treatment assignment probabilities across outcomes for each
individual in the study. We show that this allows for uniform improvements in
the power of a sensitivity analysis not only for testing the overall null of no
effect, but also for null hypotheses on \textit{specific} outcome variables
while strongly controlling the familywise error rate. We illustrate our method
through an observational study on the effect of smoking on naphthalene
exposure.
