Assessment and control for confounding by indication in observational studies

Article Abstract:

In pharmaceutical research and evaluation of pharmacologic therapies, assessment and control for confounding by indication in observational studies. IF clinical trial results cannot be achieved, the alternative is observational epidemiologic investigation. After adjustment for known risk factors, residual confounding may be present. Residual confounding is hard to exclude, but knowledge of methods to detect and control it make it possible to assess claims that confounding is an explanation for findings.
