Since 1948, the Framingham Study has followed 2,336 males and 2,873 females in order to investigate the relationship between risk factors and the development of cardiovascular disease. Data from the Framingham Study on serum cholesterol levels and coronary heart disease in men and women are show in the table below. Calculate the values for boxes labeled A through N in this table. Use the lowest level of serum cholesterol as the reference category for calculation of relative risk and risk differences.
