Neri, L. C. (Dept. Epidemiology and Community Medicine, University of Ottawa, Ontario, Canada), D. Hewitt and J. S. Mandel. Risk of sudden death in soft water areas. Amer J Epidem 94: 101104, 1971.This paper continues discussion of a reported association between suddenness of death from coronary heart disease and residence in soft water areas. An attempt has been made to establish, for the city of Ottawa, the extent to which coroner-certified deaths correspond to a classification of sudden/nonsudden. It is suggested that the predictive value of water hardness may be related to trace metal contents.
