The ORs (95% CIs) were calculated by using exact conditional logistic regression models and were weighted for obesity, ischemic heart disease, and diabetes. OR = odds ratio. Top. The effect of coexposure to asbestos (occupational) and smoking on OR were both considered as dichotomous variables. Extraoccupational exposure was combined in the control group. The baseline for comparison was exposure to neither asbestos nor smoking (86 control participants and 10 case participants; OR, 1.00). Bottom. Asbestos exposure was considered as either extraoccupational or occupational. Obesity was omitted to make the models feasible with commercially available software. The baseline for comparison was exposure to neither asbestos nor smoking (62 control participants and 6 case participants; OR, 1.00).
