To the Editor: In a previous report1 on overall mortality for a cohort of 255,868 cellular telephone users from a single cellular carrier, we found that age-specific total mortality rates for users of handheld cellular telephones differed little from those of users of nonhandheld (car and bag) cellular telephones. Herein we report cause-specific mortality in 1994 for an expanded cohort. Although the initial protocol called for continuing surveillance for mortality,2 access to data beyond 1 year was blocked by a class-action lawsuit3 challenging the legality of monitoring product safety through record linkage.
