The Focus article "Double Exposure" [EHP 107:A196-A201 (1999)] mistakenly reported that a meta-analysis of epidemiol? ogy studies examining the relationship between exposure to environmental tobac? co smoke (ETS) and human cancer was prepared for the review of ETS in consideration for listing in the National Toxicology Program (NTP) Report on Carcinogens. We would like to point out that the results of several published metaanalyses were considered during the ETS review, but that the NTP did not, in fact, perform an additional meta-analysis of these data.
