Results and discussion

Overall, no statistically significant elevations in cause-specific mortality were observed for the entire study population. However, when the analysis was stratified by duration of employment and length of follow-up, a statistically significant (P < .05) excess in lung cancer mortality was observed among workers with more than 10 years of employment and follow-up (standardized mortality ratio = 411). Because of the small number of deaths involved, and because of a prior knowledge of a lung cancer cluster at this plant, the authors (NIOSH) state that these findings should be viewed as suggestive, and that other investigations in plants with similar exposures are needed to clarify whether an occupationally related lung cancer excess truly exists.
