We previously reported5 the results of an epidemiologic study in which we demonstrated that the association between Reye's syndrome and prior exposure to aspirin was not accounted for by bias. In that study, potential cases of Reye's syndrome were reported to the investigators from a network of 108 pediatric tertiary care centers throughout the United States and Canada.
