Numerous logistic regression was used to explore the consequences away from most other risk circumstances to your organization between mortality and you may volume from climax. Within these activities years, systolic blood pressure level, and cholesterol have been registered due to the fact carried on parameters, and you will personal class (manual otherwise non-manual), cardiovascular system situation in the standard, and smoking actions as the categorical details.
