  1. Cautions in the use of antecedents as surrogates for confounders.

    Article - En anglais

    When lacking information on confounding variables, epidemiologists have used surrogates which are antecedents of both the exposures and confounders of interest.

    The usefulness of this strategy is explored in a series of scenarios for a prospective epidemiologic study wherein risk ratios relating antecedent to confounder, antecedent to exposure, and confounder to exposure were varied.

    Antecedent-adjusted, confounder-adjusted, and crude risk ratios were calculated and compared.

    The antecedent-adjusted risk ratio was useful, that is, was closer to the confounder-adjusted risk ratio than was the crude risk ratio, in 1,067 (49%) of 2,187 scenarios.
