Studies of occupational status-related risk factors in specific-cause mortality assume that the proportions of disagreements concerning the diagnoses of the cause of death do not vary between different statuses. This assumption was verified by the addition of data concerning the occupation of the decreased (collected at death registration) to a ...
Puffer R R - - 1989
Finding and analyzing multiple causes of death-rather than single causes-has major epidemiologic advantages. Besides helping to reveal the magnitude of the causes or morbid conditions leading to death, it also demonstrates that deaths are usually the result of several simultaneous or sequential causes. This article reviews ways that multiple cause ...
