Toward guidelines for the ethical reanalysis and reinterpretation of another's research.

Reanalysis and reinterpretation occur when a person other than the original investigator obtains an epidemiologic data set and conducts analyses to evaluate the quality, reliability or validity of the dataset, methods, results or conclusions reported by the original investigator. We propose ethical guidelines with regard to the duty of original investigators to cooperate with competent impartial reanalysis and for the sponsors of reanalysis and reinterpretation and the epidemiologists who carry it out. The rights and interests of these parties and of the public interest need to be protected.
