Hypertension is the most important modifiable risk factor for coronary heart disease (the leading cause of death in North America), stroke (the third leading cause), congestive heart failure, end-stage renal disease, and peripheral vascular disease.
The results of a survey or a cross-sectional study can also be used to estimate the relative risk. Kuzma uses the data from a community health survey of retirees to study the relationship between smoking and heart disease. The data are given in the table. Does the retiree have heart disease? (Is the disease present?) YES NO Total
Risk and Agile. For Agile planning and estimation (and for any type of project for that matter) there are multiple types of risk that we have to be able to understand to be able to accurately plan our work, and to be able to deliver that work in a reasonable period of time.
