Abbreviations: CI, confidence interval; OBS, observed deaths; MN, malignant neoplasm; SMR, standardized mortality ratio.

a

All results are for long-term workers (employed for 3 months or longer) and exclude workers who died (n = 58) or were lost to follow-up (n = 155) prior to the rate file begin date (1 January 1960).

b

For cause of death outcomes of a priori interest. Complete results available from the first author.

c

The SMR is the ratio of observed to expected (using United States underlying cause of death rates, 1960–2007) deaths; 95% CI was estimated based on the Poisson distribution.

d

Neurodegenerative outcomes based on US underlying cause of death rates, 1960–2007.
