What is the cumulative incidence of CVD over 10 years?

A small cohort study is conducted in 13 patients with an aggressive cellular disorder linked to cancer. The clinical courses of the patients are depicted graphically in Figure 3.2.

• b. Compute the cumulative incidence of cancer at 12 months.
• c. Compute the incidence rate (per month) of cancer.
• d. Compute the incidence rate (per month) of death.
