Here any employee-job with a disease diagnosis before the start of the job was excluded from analysis separately for each disease. All models are adjusted for calendar year, experience on the job, gender, ethnicity, whether the job was the first at the company, employee's age at the start of the job, whether the plant was a smelter, whether the plant was a union plant, whether the plant was an original company plant, and a frailty term at the employee level | |||

Model incorporating variables for presence of all five disease states in the same model.
All models are adjusted for calendar year, experience on the job, gender, ethnicity, whether the job was the first at the company, employee's age at the start of the job, whether the plant was a smelter, whether the plant was a union plant, whether the plant was an original company plant, and a frailty term at the employee level.
