A cohort mortality study of four plants of the Allied Corporation.

A historical cohort mortality study of Allied production workers at four plants who were employed between 1955 and 1961 for at least one year was conducted. This study was undertaken to determine whether mortality patterns in production facilities were similar to those of a separately studied group of research laboratory personnel working with similar materials. White male production workers from all plants combined experienced lower mortality for all causes of death combined than would be expected on the basis of the US population.

An historical cohort study of mortality among salaried research and development pensioners of the Allied Corporation.

An historical cohort study was conducted among salaried pensioners alive and receiving benefits on Dec 31, 1974, and followed for vital status through Dec 31, 1980. For all causes combined, this cohort experienced mortality levels at or below that of the US population. For all malignant neoplasms combined, workers with plant experience only showed a statistically significant excess (standardized mortality ratio [SMR] = 1.

An historical cohort study of mortality among salaried research and development workers of the Allied Corporation.

An historical cohort mortality study of research and development personnel (primarily chemists) actively employed on Dec 31, 1961, with at least 1 year of service with the Allied Corporation was carried out. These employees experienced lower mortality for all causes of death combined and all cancer causes combined than would be expected on the basis of the general US population. The degree of deficit in all causes of death combined was below the healthy worker effect usually associated with occupational mortality studies of production workers.

Mortality among automobile assembly workers. II. White males.

The objective of this study was to examine the cause-specific mortality experience of white male employees from 10 assembly plants of five participating companies. Proportionate mortality ratio (PMR) analyses carried out using both national and local standards of comparison yielded similar results. Statistical significance of PMRs was assessed using the Mantel-Haenszel procedure.
